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.

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.

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.
