greetings,

any kindhearted foummer here cares to guide me how to dampen & cover-up the front port of my altec lansing vs4121. i don't like the present sound.

thanks.

What do you mean cover-up the front port?

You dont want the sattelite sound?

do u mean cover up subwoofer front port?? ask bsl555...he modded his vs4121..manage to tighten bass.

better don't cover the front cover, it's a duct which let air out and in, and most important, might be able to balance the air pressure.
if u simply cover it, might harm the diaphragm of the speaker.
for speaker that they design with seal type, the diaphragm is different, the internal enclosure also different.

Yeah, he's right about this and only audiophile speakers like B&W comes with a special foam to be inserted to the air duct as some speakers have two firing air ducts so the foam is used to fine tune the bass for Altec Lansing's case, their speakers were not designed for such purpose so I would suggest you to avoid doing so. If you want tighter bass, add sound dampening materials inside your subwoofer enclosure, you'll be able to buy those materials from Hi-Fi shops but please take note that such materials might cost half the price of your speakers so I'm not sure whether it is a worthwhile investment. Well, you should probably auditioned the speakers with own cds or dvds before buying them in the first place.

If you wanna simple DIY mod, buy some 3/4" or thicker sponge sheer and gum them inside the woofer box. I'm sure the bass will be a lot more pleasant.

There's a few more mods but unless you're well equiped and knowledgeble of electronics, its not entirely encouraged. The advanced mods can nudge it to another level on power output and improved clarity.

thanks guys for ur reply. for ur info, i can only afford altec lansing vs4121, as my family needs comes first. anyway i simply rolled & stuffed some sort of sponge that comes with de mobo and de bass tighter now.

if i stick de sponge to de inside wall of de speaker using dunlop or shelleys glue, won't de sponge melt coz de glue is petroleum based.

Sponge doesn't last forever, it will turn to a powder substance after a few years. In Cantonese, we call it 'fu zhor'. Get what I mean? It will be messy when that happens.

Try getting decent sound dampening materials.

Sponge will last long enough inside the woofer box..at least 3 years or more, afterall we're talking about modding a RM200 thingy and most would likely dump it for something more canggih in future.
Anyway, if cost is no object (in my case) I used audio approved sponge damping inside plus other electronic mods all worth a fair amount of money and effort. Whoever I sell it to (if?) in future, after listening to it, may have an erection.

ever thinking of modifying the internal parts? cheapest yet most viable solution.

Well, if the enclosure is made of solid wood from a tree trunk, I believe that will be the ultimate upgrade for a start since the speaker box enclosure has an impact on the sound quality but honestly, it's just a RM200 pc speakers, lets not get too carried away or have too high expectations, even the top of the range speakers are still nowhere near dedicated Hi-Fi speakers.

i suggest u trade in for altec lansing atp3.
sounds way much better than vs4121.
just my opinion..

ATP3 has good bass but VS4121 has better clarity but bass isn't too shabby either. For techno music, I think ATP3 gets the job done pretty well. By the way, have you guys heard of VS4221, the bigger brother with extra 4 watts to the satellites and a remote control plus the subwoofer is housed in a solid wood enclosure. How does it compare to VS4121?

tight base???increase the base?..huhuhuhuhu....cs21 oso can put sponge it the subwoofer??...better i do myself or just send it to the electronic shop??...

The sponge is not for increasing the bass, it's to make the bass less boomy and more focused. If it's under warranty, you better not open the subwoofer, you'll risk voiding your warranty.

There's this one other mod i know of....,they get a bunch of straws(yes,the one's used for drinking) and insert the whole bunch into the blowhole/duct...,wether or not this will give you tighter and more controlled base i do not know but you might wanna give it a go......

it won't melt as the woofer is made with medium density fiber board (MDF), sort of easy name "pressed wood" easy suggestion, try put ur woofer far from wall and corner, then buy two small carpet which people put at entrance of door, prefer those braid and cloth type. put two / three layer under the woofer, it will lighten the resonance and boomy of the woofer.


it's not from solid tree trunk it's MDF, or LDF.

hell agree, i just gonna suggest that, ATP3 sounds much cleaner than the 4121.
but what to do? 4121 always sound better in open space. and ATP3 sounds like no bass at all at the rack they sell speaker.

this is an great idea, i never though of it, teorically it can alter the air flow and hence reduce the woofer effect..

one suggestion, maybe u can change the potential meter of the BASS level to higher value.
so it might be able to reduce the bass, simple and fast.

Actually there's a another technique, by varying the length and diameter of the port, maybe inserting a fitting pvc pipe of different length internally. The length of the port (since the diameter is already of fixed size) can alter the bass frequencies. The effective length and diameter of a subwoofer port is seriously taken into the design of a subwoofer for desired frequency response. Nevertheless if the speaker is somewhat boomy (due to manufacturing cost reduction of this RM200 thingy), damping the internals can be to good effect, but to my experience because they used a rather underpowered chip amp, excessive internal damping can seemingly reduce the overall bass dynamics but with tighter bass lines for sure. Its a trade-off for a nicer bass tone in this case for the 4121.

Well, by comparison, VS4221 might sound a tad better as the subwoofer is made from solid wood as mentioned by AL's website, I never get the chance to hear it but from foreign sites, they gave it 4 out of 5, considered quite a good review at this rating.

Only thing is that it will result in the warranty being void......,how old is ya vs4121?.......

thanks guys for ur guidance.

my vs 4121 warranty sudah habis la.

i'll ask my wives when they r free, to make a cloth cover & then put sponge inside de cover. after that i glue dat cover to the walls of the subwoofer.

thanks again guys. u r all helpful.

Warranty sudah habis then okaylah, if not, it's a risk. Anyway, good luck in modding ur subwoofer.

.....wives?........

Left speaker - first wife
Right speaker - second wife
Subwoofer - third wife
Altec Lansing box - fourth wife
Total = Wives

very clever, yaa.. sunauto

i meant wives la, real wives. de ones dat got two legs like u & me.

steady you.. ask wives when "they" are free...
well
one made for woofer, another one made for satelite (left) and another one for right satelite. then another one will incharge to put all of them in to the speaker, and then another one accompany u to listen and test it out to find there's significant different or not...

Sorry Bro, technical error ........ I thought you were referring to your speakers as your wives. However, speakers are men's best friend.

Errr....... not first wife in charge of bass settings, second wife in charge of treble settings, third wife in charge of subwoofer level, fourth wife in charge of volume, fifth wife in charge of on / off switch, sixth wife in charge of changing cd. KingCobra pulak in charge of auditioning the speakers with a Starbucks on his right hand.

it's ok la, bro sunauto. i know u r joking.

anyway, ur idea dat speakers r men's best friend have to be rectified, u know. marry girls dat's appealing to u & which makes u happy to be with them. speakers, i mean de music r only 1 of de tools to pamper & make de wife reach orgasm during lovemaking.

try la.. that is if u r married.

Wow, I'm learning something new from you today, lots of respect to you Bro. FYI, I'm not married yet but thanks for sharing your experiences with me. Appreciate it very much.

So, what type of music should be used for that purpose? Errr ....... is it only effective when the music is played through AL 4121? Other AL models can, ar? No lah, just wanna double confirm with you.

So, how's the progress of modding your speakers Bro? Do keep us updated on your new DIY project yeah. Thanks!

wahahaha....wanna try it when married...
wanna ask sumtin relating to subwoofer....baru datang dis idea... got shop selling only subwoofer??...i wanna buy that big subwoofer from home theatre set and plug it with my speaker...can r?..sifu's,plss help... ....

You can consider buying Yamaha subwoofer lor, they have those units available for sale from a few hundred ringgit to two thousand plus. I'm using SW-315, bought it around RM990 last time, maybe cheaper now, 10 inch woofer and 270 RMS, very good bass and it goes very loud especially when watching movies with my Yamaha amp. Not sure that's what you want. Can get sakit jantung if you put the bass level at full blast.

You're not supposed to turn up subwoofer level where you can hear it loudly or distinctively seperate altogether. Its supposed to add to the side effects without drowning the rest of the higher frequencies.
Anway, Ah Bengs don't subscribe to appropriate levels as long as it suits their whim.

You cannot say people like that lah my friend, people who likes more bass not necessarily Ah Bengs what. Besides, a good subwoofer always have room for you to push the bass further, louder and deeper if needed, they have an allowance for more demanding listeners (more refine word).

its ok...im not normal i think to be too crazy bout basssssssss.....

walaowei...sunatao...where can i find dat yamaha subwoofer??...can suggest me any places dat u know???....i wish i could listen it my self ur speaker.... ...my budget not as high as u la bro...
about 3++ only....coz wanna kumpul my money to buy souncard at the same time....

Well, there's nothing wrong if you fancy more bass because I myself do like more bass when watching my dvds at home. The bass gives the movies and music the much needed oompphh so biasalah unless you're listening to classical or jazz, you might want a neutral sounding system so that it sounds natural and soothing to your ears but if you're listening to Akon, Outcast, 50 Cents, etc ...... a big subwoofer is a must.

Yamaha subwoofer is a common thing actually, most Hi-Fi shops have it, you can try going to Sungei Wang, Plaza Low Yat, Midvalley, etc. Electrical shops do sell Yamaha subwoofer and they have various range to suit your budget but most important you listen first lah, see whether you like it or not. My subwoofer is close to a thousand last time and that's not considered mahal, my friend bought a REL subwoofer, it costs RM6000 plus but he orang kaya so different story lah, I can't afford that unless pay installment for 3 years lah. Hahaha. Well, you try and listen lor, if not Yamaha, you can consider other brands like Infinity, JBL, KEF, etc.

ok2...but bout the cables,how to sambung it to pc??...i google around juz nowand found sumting....the external souncard for pc is creative soundblaster audigy value or creative soundblaster audigy 4???...

i owned vs4121 but i dont really like the subwoofer..its too loud even when i trun it to the lowest level..any idea to slow it down..does put the sponge will help? n guys anyone know any software for sound system in pc?

u must the 1 dat like jazz or slow song rite???...hmmm...sifus sleep dy...tommorow he answer it...

yeap thanks!!!!

there's one altec lansing stand alone subwoofer for sale, i think the model is XA 301 or somethings like that. looks like a bomb, u can add it to ur ACS45.1 easily.
but for yamaha woofer, u might be a bit troublesome to set it up. as u must has an crossover before sending the low frequency signal to woofer.... not sure the woofer alone has built in crossover or not.there's a lot of things u have to take in count when u buy those theather woofer. in connecting it i mean.


scroll back previous page of this post, there's some way to tune it down suggested by forumers.

ooohh really...didnt thought bout dat....wat is crossover???....must use special tools/accesories to connect the wire??

bout the alone sub from AL...mine is cs21 la...not ACS 45.1...i dun found it in internet la...i already surf the official AL web but didn't found it la...may i know where u get the source coz i wanna see it,if can test it,much more better... bdway is it costly???

http://forum.lowyat.net/index.php?showtopic=360513&hl=
check here. he is selling.

juz found Al selling subwoofer only..model = BB2001...have u hear it before??...got in malaysia??....

PCworks,is the subwoofer from XA 301 superb with bass??..please....i really need ur expertise coz i dun wanna rugi more....

not too sure, once heard it, and i don't like how it sound. maybe u will like it, it's better u go and had a serious listen at the seller / shopping complex. before u buy.

hmmm..y i dont see these two model at lowyat r???.....is it old model???...i really wanna see how its look and sound like...but im at melaka...bit dificult to go to kl...pity me...

Those AL subwoofers are pretty old and are discontinued a long time ago, I never heard them before but I believe your CS21 will pawn them easily because newer model normally is a step forward than the older models, right? If CS21 also you feel tak cukup ooompphh, you should be getting a much better subwoofer.

Well, most HT subwoofers have a crossover inside whereby you can control the cut off frequency of your satellites (or speakers in layman's term), so you can choose say 40HZ, that means 40HZ and below, the sound will be handled by the subwoofer, the satellites handle the remaining frequencies. It is adjustable but honestly, HT subwoofers a little bit mahal lah but will give you the bass that you want, that type of solid and hard hitting bass that can cause jakit jantung, you actually feel the bass, with my Yamaha subwoofer at 40% of the volume, my table and chairs already vibrate liao and including the water in my aquarium too. Yeah, it's that powerful, with 40% of the volume and the bass level set correctly, you'll in for a surprise, that's something pc speakers cannot compare but it's not fair to compare this way lah because my Yamaha subwoofer is already the price of two sets of CS21 and you're talking about a subwoofer only and nothing else. There are cheaper models from Yamaha, as low as RM500 plus but I never tested it before, supposed to be an add on to a Plasma or LCD tv whereby the bass is severely lacking. So far, I never seen people using HT subwoofers for pc lah but the wiring no problem one, you can always modify it, 3.5 mm mini stereo plug to RCA.

wait2,i thought u also use HT subwoofer for com???....cs21 is very2 good speaker dy...juz me wanna boost more on the base ...ooo...so better dun take the XA 301 like dat...your subwoofer is to expensive to me i think coz i cant afford dat amount of money...so wanna buy a reasonable subwoofer for me...around 3++....

bout the wire,the plug use say...must DIY or got at the shop???...if got,how much does it cost??

dis question is a bit out of topic here...sorry...does anyone here have tested philips aurilium external soundcard???the quality same as the audigy from creative???...

No lah, my HT subwoofer is not for my comp, my comp is in my room, connected to my AL MX5021 but it can be used for a comp lah, the cable can be bought anywhere, less than RM8. Not very expensive, you can DIY yourself but I think no need lah, buy outside much easier.

Your budget around 3++ , right? Well, I'll search around for you to see if there's such a subwoofer suitable for your budget and no need to say lah, I know what type of bass you like.

By the way Bro Narkon, my friend said Edifier not bad, he was referring to this model, http://www.inter-asia.com.my/Review/X600%28HWM%29.jpg but I dunno the price lah, he said the bass is good. You can listen to it in their Plaza Low Yat showroom.


This post has been edited by sunauto: Dec 30 2006, 12:56 AM

ooo...my mistake...huhuhuhu...but as long can use...doesnt matter... RM8 only??...sure can 1...i thought bout 50 over...ahahaha....

yup2...my budget around dat...thanx so much bro...really appreciate it...


that model is X600 rite??...its about RM175 i think...he sell only the sub or 1 set????...
if i buy new subwoofer,how bout the old 1??...can i use both at the same time???..

If you wanna use both subwoofers, can, can, you need to buy a splitter, you know like the Logitech accessory for the PSP, one 3.5 mm plug to two earphones. That's the cable you need if you wanna use two subwoofers but you test the X600 first lah, see whether you like the sound or not, Penang don't have this model but my friend bought it from KL but I never listened to his system before because his house is very far from mine. That's a 7 inch subwoofer.

Otherwise if not, you can sell your CS 21 and get Logitech's Z-2300. Alternative method lah but pretty sayang also lah since your CS 21 is pretty new.

ooo...i have the splitter...i buy RM 3 at the shop dy...

wow...selling cs21?...a bit sayang la... ..bdway,if sell my cs21,wat is the standard price??

bout the X600,if i like the sound,better i take X600 or better i wait 1st and find a subwoofer and after dat compare it??...today i will go pusing2 Melaka to find that speaker and subwoofer...

Remember to audition Logitech Z-2300 also, compare and see how's the sound quality, sometimes cheaper speakers can give you the sound that you want like those from Edifier and Sonic Gear but the power rating is not as good as your CS21, it might have a hard hitting bass but I dunno whether it is loud enough for you or not as some most of their models are not even half the power of your CS21, maybe bass good but not loud enough for you because some people (even myself) like listening to music or watching movies at a louder volume so that the sound got more kick.

CS21, ar? If you sell now, will rugi a lot lah because people will keep on nego, negeo until you wanna pengsan. I dare not say how much it's worth now because it's pretty subjective lah, it depends on the buyer lor, if there's a buyer willing to pay higher because your CS21 is quite new, then you're in luck but got some people dunno how to appreciate and will keep on telling that it is second. Get what I mean? You don't sell first lah, tengok macam mana dulu lah, okay? CS21 is not that bad you know, many of my friends like the sound too.

at melaka dont have logitech Z 2300...edifier X 600 oso dunt have...so sakit hati...

yaaa...bout the power u said...cs21 is much2 more louder than vs4121 that my fren use...cs21 sound also more clear but the bass dont suit for me as im crazy with bass...

i dun wan sell my cs21 lah...i sayang dis speaker... sell 2nd hand sure will drop price n me rugi woo especially with people dat dun appreciate speaker like u said...

Yalor, I honestly don't encourage you to sell the speakers lor because when it comes to second hand ones (even if you bought it yesterday), buyers will keep forcing you to lower your price sampai you feel that it's not worth selling, rather throw the speakers into the sea for Nemo or Sharktale to listen than to sell them like Petaling Street prices.

So, where's your location Bro? Are you from Melaka? Don't get angry lah, Edifier X600 also cannot find in Penang but Logitech Z-2300 got la, I've tested it, it goes pretty loud, bass is satisfying but I didn't test with my own music lah but the bass definitely there but what I dun like is that it doesn't have a remote control especially when it's priced over RM500 plus.

ahahahahaha.....okie2...

im from perak actually but study in MMU melaka...so fed up 1,go here no speaker,go there no speaker... i didn't found any yamaha sub yet...juz now go survey and they only sell HT set..brand sony and etc..

honestly,i dun think i can affort to buy Z 2300 for this time being....my budget not that high... im still studying...

my budget is only about 300...another subwoofer or X600 or souncard...i think thats only choice that i can afford...the soundcard is plan B...

Well, if you can sell your CS 21 for RM300 plus, I think you can just top up RM200 like that enough for Z-2300. Just a suggestion if you manage to sell your CS 21 at this price lah. Of course, you must 100% confirm you like the sound of Z-2300 before you buy it.

thats the main problem...where i can test it...hmmm... so sad...

Well, if you got go to Penang, I said if lah, you can go to 1-Stop Midlands, Gadgetzone shop on the sixth floor, find a guy named Ah Hao, he can test Z-2300 for you, they have one unit there for testing. I dunno about any shops in KL lah, I just go there tengok and if the price is good, I'll take it but since I'm from Penang, I'm more familiar with the shops here. Sorry, can't be of much help to you.

its ok....next week sem break...balik rumah... maybe got the chance to go to penang...hopefully..maybe can go to ur house oso...ahahahaa...jokin only...

Yeah lor, can consider going to Penang lah, that shop is my friend's shop, he can give you a special price, just find that guy lor. After all, Perak to Penang is not that far also.

okay2...if im free i go ya...i contact u 1st k... bdway,do u already got the info for the subwoofer that suit for me??...can u list down the faymous brand??i wannaa google around but dunno wat brand...only know yamaha and sony but sony dun sell sub only...

seriously, you can find HT subs in Melaka Raya. You know where is the old Senyum? There's a car park beside it, and beside the car park there's an electronic shop selling speakers etc. They are more towards stage speakers and performance equipments like lightings, but they do sell HT subs. Get one active sub and get proper cables lo.

And by the way, its not a good idea to have 2 subs. Firstly, the dominant sub will overpower the weaker one. Second, different subs different sound signature, you mix them up and you'll get rojak instead. Thirdly, 1 + 1 don't always equals to 2. 2 subs means you have 2 drivers pumping the lower frequencies. At the point where the sound waves bump into each other, it will cancel each other off and you'll actually get milder bass that what you current has. Still remember a chapter on "gelombang" in your high school physics?

Unless your speakers are 2.0, then yes, getting a sub will allow you to obtain a fuller sound spectrum, but 2.1 + 0.1? I'm pretty sure it will be a waste of money. If your CS21 really doesn't suit you, just sell them off lo. There are a lot of speakers that produce heavier bass, let alone the price might be cheaper than your current CS21. Name a few: atp3, Eacan, Klispch GMX2.1...

im new here...juz 6 month in melaka...so dunno much...bout the wave....ohh...really...y sunataou nevver tell me dis before... r u really sure??..bkn x nk percaya but so sad to hear it...

k,how about i use 2 speaker in the same time??....cs21 and atp3 ....2,1 + 2.1 = 4.2 sound more ok or more sucks??

I'm not saying that Sunauto is wrong. But i do understand that some audiophiles have 2 subs in their system. That is also due to its placement. Maybe one sub at the front one at the back, or one at the left and another at the right if the room is big. Accurate planning is done to ensure both subs won't interfere with each other to produce clean and accurate bass throughout the room.

And that also is done by 2 similar subs, not 2 DIFFERENT ones.

As for you, its better if you just change your speakers. I guess you know CS21 is a decent set of speakers, but what can you do if it fails to meet your requirement? Its just like you bought a Myvi but your preference is you like to drive fast. Won't it be better if you just sell the Myvi off and fund for another car, rather than to do engine-transplant on the Myvi?

Or you can try replacing the sub of your CS21 with HT sub. I mean replace, not compliment. And please bear in mind that audio manufacturers don't design their products via the modular way. They tested the speakers to make sure they synergize well before they mass produce it. Thus you won't see CS21 using the same sub as atp3, or MX2051 with CS21's sub. You MAY try mix and match, but it will alter the original sound signature completely and the outcome might not be what you like.

owh...sound scary.... it makes me think twice...no2...think 10 times....

" I want MX5021's right satellite, CS21's left satellite, and i want atp3's sub" and here you go: mee rojak satu, percuma kopi ais satu!

Well, Bro yrh0413 is right to say that it's pointless to use two subs because if you're getting a better sub, why bother using the weaker one and if you're getting Logitech Z-2300, a complete 2.1 system, I don't think you really need to keep your CS21 anymore. For my system, it's different, my Yamaha A/V amp supports two subwoofers (must be of the same brand and model of course) but for your setup, I think, you gotta decide whether you wanna keep your CS21 and find a better sub or replace the whole system. There's a 2.1 speaker which is quite good but pricey, it's called Aego M if I'm not mistaken, that's rated five stars by What Hi-Fi UK for this year, I think some members are selling it here, should be around RM780 if I'm not mistaken, it's by AE, very famous loudspeaker company in the UK.

AegoM ain't his cup of tea. The bass is mild, very musical type of bass. The higher end you go, the more refined sound your speaker will produce. No more exaggerating and overwhelming bass that eats up details, no more thump-in-your-face. You'll hear details you never heard before. MX5021, Klipsch, CS21, AegoM, Megaworks 250D etc... all these speakers produce more accurate sound rather than emphasizing the lower frequencies.

narkon, just sell off your CS21 and get another set of speakers. You may audition the speakers you want as long as you like, then only make your purchase. Music is not about getting lots of bass anyway.

Well, there's only choice left Logitech Z-2300, the bass is boomy and loud, it should suite Bro Narkon's musical taste but I still like Aego M, it's not bass shy but it's very accurate sound pair of speakers, just love it but of course, I still love my AL MX5021 lah.

haiz....i really wanna test Z - 2300...bun cannot found it here..if the sound is like u said brosunatao..i try to sell my c21...and...bdway,if u have fren that wanna buy cs21,can promote for me??...i buy RM 420...i hope can get 380 like dat coz using it for not mmore than 1 monyh only...

bdway bro yrh0413,i know music is not about the bass but i like the bass alot more than the treble...

bro sunatou,so wat u think the best for me??...a subwoofer replacer or get new speaker??...hope can get ur opinion since u know my type of bass...

1 more question..the logitech Z 2300 got tweeter??...the sound clear like cs21??...i really like the clear sound/voice when playing music with my cs21 juz to me ,teh bass not my type abit...

MX5021 and Z2300...can give comparison to me??...

bout the aego m...sorry..i cannot afford it for this time being...

RM380 for a 2nd hand set? Most people will rather pay a little bit more to get a brand new set with full warranty instead. As for clear sound, it is because your bass doesn't overwhelm the mids and highs. You crank up the bass knob, it eats up the details. There's always a balance there.

See the main point everyone?
Now i know which brand speaker you should go to already.
Go for Logitech's dude.
Another word for Logitech's speaker is a boom boom speaker.
Hope i got this right.

sunauto: May our MX5021 rules

standard price for selling cs21??....i just use it not more than a month...thats make me sad tu sell it cheap la...coz im still a student..not rich oso...


okay2...thanx...il have to wait for along time to get the speaker...since i must sell my cs1 1st....

u staying in melaka rite??...correct me if im wrong...where can test z3200 in melaka?

Dude, see my profile over there <---
I'm from Penang, and currently in KL.
I've nothing to do with Melacca geography.
And a correction for you, is z2300 not z3200.

owh...sory2...i mistake u and yrh0413...

owh...sory..wrong typing....1 more time....malu2...

i'm not sure where can test the Logitech coz i'm not into multimedia speakers anyway. Heck, there's no hi-fi shops in Malacca also.

erm... from AL vs4212.. to CS21.. to MX5021's and Aego's..?

I have one question.. similar to the ATP3's.. I also noticed that VS4121 have 2 different batches.. one with the blue LED indicator and another one with the yellow/green LED indicator..

The later one is the one I've tested.. music sounds bad especially the mid range/vocals.. same with movies, can hardly make out what the characters are saying on normal volume..

However, when switched to playing techno/dance songs, the bass and treble excells well, but can get a little bit woozy when paired with PSC805 with QSizzle and QRumble enabled..

Any VS4121 users having the 'earlier' blue LED batches care to give some comment..?

if ur fren,wife know...please inform me ya....

told ya there is no hi fi shop...

I though all VS4121 is yellow LED?
The blue LED if not mistaken is VS4221, or something like that.

Nonono.... I've seen a VS4121 with blue LED!! But I only heard Windows loading sound through it.. definately there's something different than the yellow coloured one.. sounds 'deeper'...

This post has been edited by ATI.Bob: Jan 1 2007, 05:06 PM

I've the VS4121 with blue LED, but I've never heard of the yellow LED version, so can't tell the difference


BTW, I wanted to mod the amplifier, but I can't figure what I should mod, any suggestion?

I dismantled the subwoofer and below are the pictures of the amplifier

If you don't have access to a desoldering and smd device workstation, forget it. Conventional removal may risk untold pcb damage.
Couple of chips there can be swapped for better ones. Perhaps the easiest and DIY mod is to obtain and install fairly thick acoustic sponge padding onto the internal walls of the woofer box. The TDA7377 chip is somewhat a bit underpowered.

Aboy....,there is one at SENYUM lah.....,i saw it there like 3months back......

There's times I regret selling off my previous AL Model 321. The electronics and subwoofer was significantly superior.

Well, my old junk AL ADA305 also sounded better than some of the precier AL models too because the subwoofer is made from solid wood, it might be underpowered but the sound is more superior and the total weight of the speakers are indeed heavier than most of the last AL speakers. Cost cutting measure I guess.

aiyooo...where is SENYUM r????...me new here...i ask my fren oso he say dunno...is it near MP???...

hi guy! i see u guy saying modification on vs4121, i wonder , how to open the subwoofer
case ? there is no screw

If your vs4121 is under warranty, do not attempt to open it. Not worth voiding the warranty just to take a peep inside, you know what I mean?

Someone has already provided pictures of the internal components here..should be enough isn't it?..
