Well, I have a total of 5 subs in my HT setup, and currently have three running on front L+R, and two on Rear L+R. Processor has center "small" "no sub" Front "Large" and Rear "Large". So center + LFE bass gets routed to the front.

The front subs are 2 Polk SRT's, and one Sunfire True Sub. The SRT's are great, but begin rolling off at 20Hz or so. By tossing the Sunfire into the mix, setting it's xover to 35Hz, it adds to the bottom end. Also, I'm spreading the bass over 3 subs...great dynamics! In this configuration, the system is capable of 125dB from about 18Hz up.

I have tried the following:

Sunfire run off the center channel. That means center was set to "Large". This was a pretty good configuration. The center channels didn't seem to mind the "Large" setting.

Sunfire dedicated to LFE. Set Sub to "On"; Center to "small", everything else "Large". I felt that system dynamics took a bit of a nosedive at higher SPLs; it definitely sounded strained when asked to reproduce 110dB and greater. I'm sure that a more capable sub would work fine in this configuration.

I think that a sub (or two) on the rear channels adds some great effects. More and more movies are utilizing lower freq's in the rear channels---not only action movies.

Hope this helps?
