Why dual subwoofers ?

More is always better right?

It's either easier for placement because you have two subs to make up for any errors, or harder because you have twice the errors.

I really have not made up my mind on this one yet.....

Robedk, I belive that the dual subwoofer outputs on your
preamp have the same .1 signal. The second one is for use
on large rooms where one sub might not be enough. Another
reason is when one wants to use two small ones instead of one large one and blend the system with the room decor.

I use two subs on a 2 channel system, one gets the signal
from the left channel and the other from the right one.
The sound is awesome, they are big (Linn AV-5150) but the
sound (bass) did improved a lot. I started the system with one sub, didn't like it because I felt that the bass was coming from one side of the room. When I got the second one
the image came back. As stated by Themadmilkman,Slappy & Vvrinc the use of two subs will cancel some of the satnding waves and the bass will be cleaner. Hope this helps.

Well, I just ordered the second sub( another Velodyne HGS 15 ). BTW, the rest of the speakers are B&W Nautilus( 802's - mains / 803's- surrounds / HTM1 - center ). I'll let you know what I think once I get it in the system. Thanks for the feedback !

Actually, I have couple questions. Since my AVR does not have two outputs for two subs, is it true that I can use a Y connector for dual subs? If such is the case, does any A'gon member know if the sound is as comparable as the AVR w/ two outputs for 2 subs? If we I want to go w/ 2 subs, should I get a new AVR w/ two outputs for dual subs, or should I save the money by purchasing a Y connector. I have the Yamaha RX-V1400, which has the microphone for automatic room calibration, and the AVR is used as a pre/pro. The amp is a 5-channel Marantz w/ 150wpc. HT setup is 5.1. AR speakers, Phantom 8.3 (X4) for main and surround speakers, and Phantom 252C (X1); 50-250w, 40Hz-20K; 89db sensitive. Current sub is Polk PSW350, a 150W powered amp. Thinking of getting a HSU VTF MK-2 as a second unit since the store is only few miles away from my house. I have been contemplating b/c room size is only 12'X13', and I need to cough out another $500+tax, and not sure if 2 subs would drive my neighors crazy, which is the opposite of what these posts have stated, i.e. 2 subs should be less boomy as sound and dynamic range or sound freqency should improve. There is a 30 day trial, but you all know what happen when I carry home that heavy sucker with many rave reviews. That is why I want to remain objective, not bias, and listen to your valuable advice. Thank you all for reading. Any input is greatly appreciated.

Robedk,

What are the dimensions of your listening area?
