subwoofer question

Not a lot of stereo information below 40Hz but wont two subs in stereo be preferable to two in mono?

Bob, Marty so if i hear you correctly youre saying there is no stereo info or localization info below 80-90Hz. So the superiority with two subs would be cancellations of node and downside if you take money into account would be you could buy a better single sub?

Marty,

I have a Onkyo 905 for HT duty so it has Audyssey.
For HT I have the sub connected from the sub out on the Reciever, but for 2ch I have it from the speaker so the reciever is not involved.

I guess for HT the Audyssey will be used but I still think the Room corrector in the JL sub might be superior to the Onkyo?

I use a 10" sub because I want the speed in the base to match the speakers however Im still contemplating adding a second sub....

Marty,

I should add that I cross the sub very low for two channel, below 40Hz, to best blend with the speakers, so going by your 100Hz limit I could go with the mono setup. I would still use the JL room corrector.

Marty,

I read through some of the HT/Sub posts but dont find any info on bigger driver being faster, maybe I didnt looke close enough, can you point me in the right direction?
I have tried using the reciever with its EQ in the 2ch chain and the sound is clearly worse for me.

Bob,

when you say the room is too small for bass management from the subs and priferable to go with the full range EQ, what size would you think is approriate before that problem dissapears?

Also what do you guys think about mixing same brand subs but with different driver sizes, a 10" with a 12 or 13"?

Bob, Marty,

thanks for your answers!

We may be down to hair splitting now but if we take two similar subs like a JL Audio Fathom F113 and F112, these are very similar, do you guys still think the F113 ar faster?

Marty,

thanks for your answer! I must add that the "clearly worse" was for 2 channel listening. I think the more electronics in the chain is not beneficial.
My system is 95% about 2ch and 5% movies. So its 95% musicality and 5% big effects for me. I run the full Audessey for movies though. but for 2ch the reciever is out of the system.

If your highly damped theory would be applied to two subs from the same brand, in my case the JL Audio Fathoms, it would probably come down to size of box as the decider for if the sub is "fast" or not, but my guess would still be the 10" is faster than the 12". I havent heard both in my system but I found the 10" faster than the 13" in the F113. But still if both the F110 and F112 are equally damped your theory might extend to the possibility of integrating different sized drivers successfully.

Marty sorry im not following when you say Box size is not key then say 13" Box will be more damped than 11" for a 10" driver, i.e bigger Box more damped. So if i read you correctly you say a f113 can be faster than a f110 due to having a larger volume relative to its driver? I guess the other parameters will be pretty similar between these two subs so pretty well controlled experiment here. The other hypothesis might be that the smaller element is lighter and therefore moves faster. Do you see any drawbacks with a highly damped sub versus a ledset damped?
