Is good to know some numbers and specs. We just try to get info to give some idea. Listening in actual in showroom or other room is also the same thing. Just to get some idea. Than of course the decision is go or not. Maybe is still 50/50 but that is what we get. I am bit more kiasu to stick with brands that I know is good for me. Usually i donโ€™t audition or even bother to check on specs. I just go with my gut instinct ๐Ÿ˜๐Ÿ˜. Happy hunting

absolutely... plus we are also human, what you can hear vs what i can hear will be different... not to mentioned what you like vs what i like... biggrin.gif

As long as you keep open minded on selection, there will be many good choices. Just not like some who swear by the numbers and measurement.ย  blush.gif

...suddenly my 10-year old 10w 1% distortion amp sucks in my 60ft hall... time to look for some super 1000w 0.00001% ultra-linear dsp correction amp... and my zero bass (85hz low only) 4.5" dinosaur-tech paper cone bedroom speakers should be chopped up as firewood...because computer speakers can go lower...

30+ years of hifi, 10 years piano to grade 8, hundreds of hours attending live philharmonics orchestras and recitals, countless beers enjoying live jazz bars... all useless... because you only need to read spec sheets and reviews... whistling.gif

anyways enough ot wink.gif

ps: i also went for audiometry tests... i know which ear has a slight dip at what frequency... but otherwise perfect hearing with normal high end roll off for my age... lol

Hi..i want to connect my laptop to speaker...the only input to speaker is using audio optical ..so 3.5mm audio jack to optical converter to convert my laptops 3.5mm jack to optical audio? Does it work?

if macbook... some audio jack is also optical out...

yes will work but not sure of this cable can cucuk deep enough...why not try the cheap RM5 toslink cables first...

imho... i'd consider a bluetooth receiver with optical out for more flexibility...

you screen first shortlist here we give you our opinion... i'm sure you have looked or listened to a few...

i would go with more musical subs to add that extra bottom ends... no need to shake you neighbors' house down

dont think you are asking in the correct thread.. but anyway..

does your laptop support optical output? if not, i dont recommend this type of conversion.. your laptop soundcard change the audio from digital to analog to output to 3.5mm jack.. then you need to do a conversion to digital back using ur cable then ur speaker will again change from digital to analog  doh.gif

does it worth the trouble?

if you are serious about audio and willing to invest, you can consider DAC/Headphone Amp like Fiio K3.

connect it thru usb to your laptop and the digital audio out from k3 to your speaker. the good thing about this is you can still keep this unit even after you upgrade your laptop or you want to use it on your desktop. Fiio that i m using can be considered as upgrade over most of the build in sound card that laptop/desktop offer. The best of it, you wont go thru the conversion over conversion where you will lost audio signal every time it get converted.

this is a good choice too...

Currently looking at Q Acoustic 3070s, not sure it is a good buy or not and I kinda agree with u, I dun need a sub tat can shake my neighbours house down ๐Ÿ˜€
*
i don't think this is a good match or good deal

your floor-stander easily down to 40+hz... these kind of subs usually around 50+hz and have steep roll off, meaning you don't get much volume below 50+hz... these are best match for small/tiny bookshelf lifestyle system or HTIB package

40hz is important as the 4 string bass goes there and you're already covered... nothing much goes lower than 30hz except concert grand... movies will have artificial sub-bass notes for the senses but you're not watching explosions on every movie and they don't start exploding from start to finish... laugh.gif

i would suggest the more traditional 10" to 12" square box type subwoofer that should get you down to 30+hz or lower... the main thing to look out for is port chuffing sound when you demo at highish volume...

thx for explanation bro, my setup intention was 50/50 (music & movie) build, which mean i have to look for 20hz freq range sub right ?
*
movies are full of music too... only minuscule % of time goes into sub-bass

30hz spec subs will still give you 20hz but just not that loud

20hz spec subs prepare to spend at least 3-4k lor...

ideally la if you dont care then ignore.. if not 25hz to 30hz is also good enough.. most of the floor stander can do around 40hz d, you will feel it.. but find something 10inch min you cant defy the rule of physics.. u cannot bawak kancil and try to challenge 200kmh
ur 3070 is dual 6.5" it certainly will play louder at certain freq but you are missing some freq in the other hand.. by right your crossover setup should be 80hz at ur 3050i and below 80hz is sub realm.. u bought a 1.5k sub that give u 50-80hz.. might as well i pay yamaha which able to give me 25hz - 80hz that cost <1000.. of cos audio quality between the two sub is another topic to cover

unless u r really pro and you figure out you dont need the extra low frequency and you found your 3050i setup you try out all d but missing out the chunk of 50 - 100hz range then 3070i is something you can consider.
*
if i have a good floor-stander... i'll let it play full range 40hz-20khz, and just tune my sub to fill in below 40hz... no reason to crossover at 80hz and constrain my floor-stander...

with this approach you can have a more budget friendly sub, and your system will sound more coherent... as any flaws from the sub is kept in check as its only heard less frequently below 40hz... wink.gif

very much agree bro.. but that will required good floor stander and amp.. low freq need a lot of juice from amp.. i dun have both so i rather my sub take the punishment and relief it from my amp + not so great fronts  mega_shok.gif

you made me check his speaker spec... lol... 91db sensitivity... no problem ah

my floor-stander is 92db i drive it with 10w amp volume dial at 9...any higher my wifey starts to complain too loud... haiz... wink.gif

anyways... most amp has enough juice... but as always trial and error to find the best match

Disagree.

I have a pair of of Ascend Acoustics Sierra Towers, they are rated down to 40hz but in-room is about 31hz and are very efficient too (92db/1m). Sublime towers but they benefit from having a crossover of above 60hz. Want to know why? Because unlike your sub(s), the front L and R can only be placed at ONE specific location of the room to form the "golden triangle" between it and the listener.

Bass is all about gelling it with room modes, which you have the freedom with sub(s). I can tell you with absolute certainty in a non-odd rectangle shaped room, 2 subs along the middle path of the long walls of the room (the L and R walls basically) crossovered with the mains at 80hz (in my case, I go as high as 90hz), is MUCH better than subs in front of the room with the crossover down at 40hz.
*
ah.. this is getting into room tuning... and you're also right...

sometimes you have to crossover at higher frequency to tune down the fronts so that it goes better with the subs... i can fully support this... my last line to Kevin "...but as always trial and error to find the best match"

you have the benefit of good towers and good twin subs...this offers you so much more flexibility... whilst i was making a point that if i have good towers but a crappy sub, then perhaps my strategy is not make the crappy sub front and centre (pun intended) by crossing it high at 80hz...

dont say your last line la doh.gif sound like u sudah tak boleh... i am always here we can always share...
i forgot if i have share to you or somebody else...
i had tested... i drop my crossover 60 i lost the dynamic and detail from the fronts.. my floor standing can do 40hz..  the bass is better but i lost the dynamic so i reverted to the setting and let the sub do the job instead.
even for thx they recommend 80hz crossover thats why i always recommend ppl who new in HT to start with 80-120hz.. one day they will become pro like u they will know how to play with.. innocent.gif
*
haha... okok

no I didn't see your feedback to somebody else... it's true, what you're experiencing is amp unable to "control" the speaker... audiophiles call it amp/speaker matching... and it's not about watts & ohms but more around damping between amp/speaker

thx has a different objective...they are after dynamics... so by limiting excursions below 80hz, it's easier to design & deliver the power and spl...at higher hz, damping requirements are also less... anyways enough rambling from me... sweat.gif

And that's why I said earlier to doi0728 not to buy fart boxes at RM1.5k, save up till he can get a SVS sub.

I think got many reasonably good subs around 1.5~2k from reputable hifi makers, obviously not to svs performance level, but also at substantial lower price

afterall not every one needs a Mercedes... plenty of people happy with Toyota...

i will pass on this if i were you... 35hz @ -6db won't sound that low tbh... you wanna find something 30hz/-3db, if cant maybe settle for 35hz/-3db

you made me work.... mad.gif

desa has a kef q400b, klipsch r-100sw...and few others... https://desahome.com/find.php?vipflg=N&cate...ubcats%5B%5D=SW

others... mission ms-200, monitor audio mrw10...and a few more...

priority based on spec and my pref for sealed subs... kef, mission, klipsch, monitor audio... you may want the monitor audio because got white... lol...

as mentioned earlier... for 20hz you need ~4k budget... putting in differently extra 2k to go 10hz lower...

I know...there is nno argument between woofer and subwoofer,  biggrin.gif but since I have 4 12in woofer, I would like to drive with it first. After getting my new amp, if it cant drive it, then I may consider a sub.

This is the speaker I have

This kind of speaker got good bass?
I had something similar before, sansui speaker, 3 way the woofer cone so huge 12.xx", but still need tone control maxed in order to screw out the mid bass, and it's not going deep low below 40Hz tho... Good for hall disco usage, but not for movie watching taste, haha.

no real bass.

these type of 12" is typically used to manage sensitivity and linearity vs spl...
