2 subwoofer???

Hey Duke, can you expand on your "second school of thought" comment above. I run dual subs and am all ears on set-up advice. You too Sgr and Rives. My primary concern is 2-channel audio even though I have HT in the same installation.

BTW Uru975, the bottom end of the Focus 20/20s is tough to match. I was a very happy owner of a set before getting Whispers. Even for HT, there is no need for a sub with those speakers...just lots of amplifier current!

Thanks for the responses everyone. I am restricted quite a bit in where I can place my subs, but I will try to turn them to see how this changes things if at all. My room too is over 3500 cu ft, but my subs seem to have plenty of oomph for it. FWIW, placing audio points underneath made an audible and measurable difference.

In addition to Rusler's question, when running two subs do people here like to run them in stereo or mono?
