Separate subs for bass management & LFE in a surround set up


I'm building a listening room & going as wild as I can. 12' high x 20' w x 28' deep and I want to do 4 subs in the 1/4 from the corners config. I am thinking about having the two front subs play the bass-managed signal from the LRC & surrounds and the back two subs play the LFE. I can also direct the left side signals (L, LS, LRS) to the left front sub and the right side signals to the right front sub and send the center to both. I have a Trinnov Altitude 16 so I can send whatever signal i want in any config to any speaker. Both rears would get the same LFE obviously. 

The thought is for music recorded purposely for surround to keep the low end info on the same side it came from. Especially for live acoustic stuff where they recreate the room. I realize you can't directly localize a sub with your ears, but it seems since I can send the signals that way I might as well and there will be some advantage. Or am I just overthinking this?

Again I agree with Eric.

As you must be noticing multi-channel music post production is quite interpretive yet still manages to convey space for the most part. I'm guessing your extra low frequency concerns are more a matter of your rooms reaction to ELF and your personal taste.

I've set up my two channel system in three different homes, including one with similar dimensions as yours. Running my TWO subs in plane with the main speakers in stereo was only slightly worse than in mono and was confirmed by my subs built in Room Optimization software.

While four subs would completely change my situation I think I'd still be pessimistic regarding ELF stereo imaging unless you run two at unusually high crossover points. With the added flexibility of using four subs experimentation should provide you with far more knowledge and hopefully the results you're seeking.
