Otai, sifu, taikor...
i plan to upgrade my sub and still thinking which one is better for music and movie....
currently i'm using downfiring...
and is it important we have a good cable our sub...

This post has been edited by matyeo: Mar 15 2010, 08:34 PM

my 2 cents worth............i think the down firing sounds better

The difference in sound (to me) isn't really that obvious.. I believe they are both for different placement rather than difference for music or movie

From what i heard through a colleague, that downfire sub you feel as surround bass fills your living hall..

Im not sure if he was right..someone expertise on this could correct me..

Cannot used downfiring sub at apartment maa.. Neighbours that lives below your apartment will get fast HIGH BLOOD PRESSURE due to LFE kicks

Hehehe, who cares..but not so loud of course ...

Bro, that was hilarious

those SVS PB and SB subs are front firing. what say you?

I have owned both the down firing sub as well as front firing. As a matter of fact, I can do the test easily since I have both of them with the same driver and same amp.

If it is being set correctly, the bass is perceivable to be same . The setting and placement for a sub is important. Get it correctly, it will 'disappear' in your room and blend well with your setup. Just my 2 cents

taikor... which one do you like, interm of easy to setting and placement ...




"From what i heard through a colleague, that downfire sub you feel as surround bass fills your living hall..

agree with this statement....i can feel that

In my case for SVS, the PC since it is a whole lot lighter. Downfiring and front firing have equally same punch and it fills the room as it should be if being set up correctly.

The PB is a monster to be moved around. PB12-Plus itself is a back breaking 127lbs while the PB13-Ultra that I am having in the HT room is a jaw-dropping 155lbs. That's about 70kg!. PC13-Ultra is only 90lbs (41kg). So, it is easier to move the cyclinder.

cylinder can peluk so easier to move. make sure hm not around or she might be jealous

Setting and subwoofer placement is a very subjective..need more experience to find sweet spot...I'm also not expertise to get ideal subwoofer placement.Need to crawl mehh From what I know correct subwoofer setting is you will not know its location when LFE kicks bcoz of undirectional sound...Correct me plz.. Currently my system leads by PSB subsonic front firing (Old model ).I'm just setting my sub volume to 9 o'clock and crossover to max due to I let my AVR to filter LFE signal (THX recommended=80hz).So far it's ok for me but for guys that likes kobabowww they will feel my setting lack of punch . I also can feel it's power whether in low volume.Both front firing and down firing have their pro's/con's.

tks to all... i think my next upgrade still down firing same like my current sub....

My subwoofer is front-firing type.
I think i'll attach some rubber footage on my subwoofer and keep it firing down

i think down firing. ... else my ear will hurt....

The difference are from where you place it and what you place it on, tiles, carpet, behind the lounge etc.

subs are designed to be hidden under chairs and generally out of sigth and since the sub fequence is a large wave form you don't need to position it anywhere within the stereo space strategically.

For me down or up is just a marketing thing. If you have to ask which is better then you aren't listening to either of them. Try befoe you buy.

yaya, agree...

woofer is for making the floor boom boom and our heart beat pound pound....

I will do same as you do...

bro ..polk audio DSW-pro600 downfiring sub but this sub have option to make it as
front firing...
check this.... http://www.polkaudio.com/homeaudio/dsw/index.php?s=dswpro600

For me different sub will giv different effect.
But the must different is ported or sealed.

Anyhow just believe in ur ear and find a good placement..

Guys...what say u if i think...

Frontfiring good for music and downfiring good for movie.....

the sub good for music is the sealed one and not either front or down firing

what do you mean by sealed, do you have a picture to share...

maybe like paradigm i think....woofer inside box....

sealed ones are those that has no vent holes in the enclosure. the entire sub is sealed and there's no port.
requires more power to drive, and requires special drivers to be used.

for example velodyne spl1200u or the new incoming svs sb series. a lot more out there. u can google.

I prefer the downfiring... if ur floor is hard floor (marble or granite tiles) the reflection of the bass very nice.

My old house, one of the room is wooden floor and i put carpet on it. Then i place the downfiring woofer and blast some movies. The effect is nice where the whole floor is shaking when u're watching the movies...

Heheh...

I wonder how much would the new sb12-nsd go for.... if under 4k shipped.. im gonna grab it.

grab one for me too

aiyor... i cant compare to tauke arremie leh.. my stuff all cheap cheap only you shud go for pb13-ultra

The reason i thinking of sub is cos i listen to modern song not shiok... totally neutral and cant pull me in...

I still considering lah, hopefully can save up the budget, might have to give up PS3 first. FF13 T__T

i dont use sub for music coz my music not boom boom pow type. a bit of tight controlled bass good enuf for me

very nice very nice when watch movie whole floor and sit is shaking...

yes man, before the subwoofer dominate it all, i'd prefer to turn it off and enjoy variety of music

me also but some times only , my floorstand can reach low freq at 20hz....

Ya, but unfortunately for me, my speaker dont have much so called sub bass. Highs, mid, mid bass all excellent. :0)

I did consult to a Dynaudio dealer from US at avsforum. He told me, dont upgrade amp first. Get a sub cos my main complain was listening to boom boom pow not shiok. But audiophile vocal (i listen a lot) is actually sound good.

When i used my friend's wharfedale 8.4, the bass was enuf for me... even Narnia - Prince Caspian track, wow, superb low bass. But on my speaker, tat bass information is just not there.... my bass rolloff at 40hz.

no way man. even sub suffer to get that low

today i go to audition velodyne SPL1200Q = SPL1200U at AL audio
SA played to me 2012, at the bigining i can't feel the powerful of this sub
bcoz he set all speaker to large...
second round i ask for small setting... so awesome...
accly i don't have enough time to feel the music bass ...robie william concert...ok la
SA told me this sub need at least 20m to warm up after....

SA told me velodyne is the best sub, 2nd is sunfire and 3rd JL....agree arr...

they are all good sub. depend on ur preference and what u mostly use for.

oh and depend on how deep ur pocket is

spl1200u - rm6.7k...i think expensive la can get more cheap i think...

At usable Hz? It must be an ultra expensive floorstanders Specs on paper is most of the time deceiving to say the least.

To try it out, you will have to download the test disc to check whether it does produce sound at specific Hz range.



Yes, I do agree.

I am staying away from giving any comment on the subs ranking

of course la bro that one only on paper...

taikor htkaki also said only expensive one... can reach that low....

My current sub can reach 25hz (spec on paper) and sometime when i'm not use my sub,
set my speakers to large and fine tune EQ...for this case i think my floorstand can give
solid bass as my sub done...that what i feel...
i made this setting while listen to stereo mode...

If it's 20hz above 90db, then it's yes.
Else

matyeo, what sub that you are using right now? Normally, most sub would have start to roll-off at least 5-8Hz before the lowest Hz stated on the paper .

I have posted the frequency response graphs of many renowned subwoofers in 'The Official Subwoofer Thread V2'. Worth to check it out .

The JL Audio F113 is indeed a good subwoofer for its diminutive size. Small yet powerful. However, it is not cheap. It will blows the Velodyne DD-15.

No hard feeling to most of the ppl out there . We are still too engrossed with 'boom boom' LFE, in other words, only loud bass . Subwoofer isn't only about explosion, gunshots and so forth. It can actually create a better ambiance with the reproduction of background music / effect, making movie watching more enjoyable. It can create the tenseness in a movie if it is able to produce clean bass with ample power.

Most of the setup that I came across is either being set too loud or drowning the rest of the speakers making overall SQ muddy and muffled . I ain't guru in this but still trying hard to learn more about this 'unsung hero' (subwoofer) in today's HT system .

Very agree wit u.. "...Subwoofer isn't only about explosion, gunshots and so forth. It can actually create a better ambiance with the reproduction of background music / effect, making movie watching more enjoyable. It can create the tenseness in a movie if it is able to produce clean bass with ample power..."

Some sub not boom boom boom.. but it bring the music and movie sound forward or make it more alive..

For me too much KEBABOWW will make your movies/music feel muddy.Its very subjective.Most important things is how you control your subwoofer not subwoofer control you.Of course expensive subwoofer will give great LFE but without knowledge you will make it suck and you wasted your money.SIFU HTKAKI also still learn eventhough he's SIFU

Taikor...my sub only cekai one JBL pb12 downfiring 250w rms ....
i read manual it state...

FreqResponse: 25Hz – low-pass crossover setting

Low pass crossover - 50hz-150hz

how do we know our sub start roll-off freq...

taikor...reasond why i join HT forum is to learn from otai2 here so good to have someone like u full of knowladge....
i'll check your subwoofer thrade......

Taukeh you would need to look for the RF graph for JBL pb12.

Not easy to look for JBL PB12 graph.

Taukeh ronald, can tk photos and send to me? Kamchia...

Btw, some 'precious' loudspeakers will make its way here by next weekend You do have one of it

Peasant setup boss. Very paiseh.
After seeing Sonus Faber + McIntosh and JBL Everest + LX90
Can only


What is the loudspeaker?
Btw want to ask if Tat Chuan having RF83 on demo now?
Feel like kacau Wong for an audition.

This post has been edited by ronaldjoe: Mar 18 2010, 10:49 PM

u need to wait 2 months for that

Alternative way is to kacau Anthony down south.

Yes. The last I checked, there is only RF-63 on demo.

Hi,

My 2 cts..

I dont tink there is much appreciable diff between a downfirin or front firing sub if its alrdy figured out in its design phase..
SvS box subs used to be downfirin .. I knw mine is de old dwn firing one..

Aesthetics wise thou'.. I prefer de dwn firing one as I beleive de front firing looks smaller then my old thumper..

Tats jus me..
D

so..from my understanding we need other gauge like SPL meter to get accurate LFE from our sub...am i right...?
what about calibration tools which is provided ....for example velodyne come with audyssey...

It's either sms-1, anti-mode or as-eq1.
As for audyssey, it's audyssey pro that have proper resolution to get accurate lfe.

bro..is it SPL meter we must(wajib) have to fine tune our sub....

i think i need to know what is "sms-1, anti-mode or as-eq1"...do you have link

Google bro.
SPL only measure db at desired freq selected.
SMS-1, anti-mode, as-eq1 calibrate the sub for the inherent sub/ room weakness.

Read up : http://www.audioholics.com/reviews/acousti...s-as-eq1-sub-eq

i thought that was same tools...

For as eq1, no need to read.
Just borrow one unit from taukeh to experience it.

Boss, next time I'll loan it to you when the SB13-Plus is here (within 2 mths or so). Ok boh?

Hope to get a 9.2 proc first.

usefull info.. Thanks

Majority forumers here using downfiring sub...Looks like mine only alone with cikai front firing sub.Shame to talking mehh

Cikai front firing sub, if with good placement and turning plus sound treatment also can complete with branded downfiring sub..

bro..buy another one ...down firing mehh...2 sub can boom boom powww your living halll....

I believe majority are using front firing sub.
Looking at recent trend, new subs are configured in front firing.

Wah..... mine also 'cikai' sub liao



Yes, most of it employing front firing driver. Down-firing or front firing, if you get the correct setting for either one, it should be similiar in performance with non perceivable difference.

Do urs think anyway can modified the cikai sub.??

I have no intention to modify my 'cikai' sub for now as it sounds very good to me

IMHO, front or down firing doesn't matter much. If you get the correct position and setting, it will sounds just as good. Been there, done that (same power rating (amp) and same woofer. Only design is different)

agree wit u too, as i experience it with my own.

start from i test&buy it then setup at my parent house and then move to new house.
All of then giving different impact cos palcement and also room condition.

so i really believe in room treatment that can help in our system alot...

anyhow i still thinking of change the internal cable to bigger cable...

ur think can it help?

Changing cable will not make the sub goes lower with usable output. People change the cables for speakers to get better tonal quality. I doubt your sub will sound tighter with thicker cable. The limitation lies in the woofer itself. LFE is different. Better focus on room treatment.

Public cinemas use front-firing subwoofer.. shake all audience

OK, thanks bro..

Mine as well. Front firing. Must get hold of a downfiring sub to give it a try.

I'm not alone with front firing sub. Now i'm in progress to learn some room treatment from others sifu's

You need to dig sifu ycs's thread for room treatment. There are a few others who are quite knowledgable in aocustic treatment. But, seldom see them around nowadays.

A few others went DIY path. Reix is one of them who did his own panels.

To start it off, here's a link for your leisure reading :

http://www.audioholics.com/education/acoustics-principles/

try audioquest sub 1 or sub 3...... ......... racun ni....

Walawei..not afford to own it maa

modified... .....what do you think we can replace..woofer....?...crossover.....?
i think very hard to find lah...or the price too high...

I am using the QED Reference Subwoofer cable as well as SVS sub cable. Not that expensive. Sub is sitting on Auralex Gramma to reduce vibration.

my audioquest sub 3 also not that expensive also boss, i bought it 2nd hand but very new and excellent
condition..... i won bidding on ebay....

taukeh...what is Auralex Gramma, do you have picture...
can we used that for any oyher sub....

boss, I presume you are using PB13 Ultra, right? And Auralex Gramma can handle that? I'm having PB12+ and I can't fit Auralex Gramma under it... thinking of getting the Great Gramma

Is't for downfiring only

Here you go.

How much is that? Where to order?

http://forum.lowyat.net/index.php?showtopic=1211758
Last time I did a mini bulk (zero profit & charity) bulk for svs owners.

You can get it from Center Circle.

Added on March 23, 2010, 2:12 pmBoss, you didn't let me know you wanna let it go. I just got another piece of gramma 3 weeks back.

Added on March 23, 2010, 2:12 pmBoth. Front and down.

This post has been edited by ronaldjoe: Mar 23 2010, 02:12 PM

No boss lah, small fly only I'm not sure if I should get another gramma to use it together with the one that I have or get a great gramma instead. So you are having 2 gramma for 2 sub or 2 gramma for 1 sub?

Boss. Now it's one gramma and one great gramma. A great gramma is sufficent for PB13.
Gramma have no problem holding PB12. It's just out the range of the 6 spikes under neath.
No harm if the wooden body of PB is having contact with the gramma.
Yonggoh, Bryan, Htkaki are all using gramma with PB.

I took out the 6 rubber spikes from the PB13-Ultra and lay it on top of Gramma. No issue thus far. I had another Gramma for PB12-NSD while Subdude is for PC12-Plus.

The problem is that the 6 spikes just barely touch the edge of the gramma... Ok will give it one more try when someone can assist me to lift the sub

Added on March 23, 2010, 3:11 pmI was thinkg removing the spikes too but but due to its size and weight I would rather have the spike on...

What 's a different when using gramma under your sub.Pls share with me coz i'm never heard about this things before
