They re all symmetrical and really the only places I can put 4 subs without stacking them in the front. I have a fireplace to my left in the middle and french doors to the rear in the middle.
An SMS-1 can only output 1 EQ'd signal. IOW, you would EQ the 4 subs as if they were 1 sub. That is fine as what you hear is the combined response of all 4 subs, as if they were 1 sub.
However, level setting in a system were some of the subs get more room reinforcement than others is probably better achieved with gain-matching than level matching. Here is a thread that discusses it:http://www.avsforum.com/avs-vb/showt...=gain+matching
In your room, the corner loaded subs will get a lot more room reinforcement than the non-corner loaded subs. They'll end up being set lower than the non-corner loaded subs. The non-corner loaded subs, being set higher, will reach their limits sooner, compress and distort sooner. To even this out, the gain-matching technique is a better option. Try it and see.
