Firstly, heed the advice from MC/Noble101/and especially Duke LeJeune.
Secondly, I will divert from phase, crossover frequencies, gain, etc. and instead share my experience regarding subwoofer placement.
I am running four subwoofers (yes, the AudioKinesis Swarm). Two are mounted up high facing the ceiling. Their heights vary with one 12 '' and the other 18 '' below the ceiling.
Duke mentioned in an earlier thread that any subwoofers mounted above the room mid height contribute to the vertical plane, thus further reducing standing bass nodes.
My A/B testing (4 on the floor vs. 2 on the floor with 2 up high) in 2 rooms (10 x 12 minus closets and 12 x 16 living room) at my previous house along with over a year at my new house (also A/B testing between a 13 x 16 vs. a 15 x 19 room) all clearly confirm a noticeable all around improvement.
Hope this is helpful to you!
