Since the swarm-is-the-rage, I'm wondering how this config would sound: A 15-18 sub (single) in the middle, two 12s (left and right), and two 8-10s (further left and right). Another reason to play the lottery!
In my 28 year listening experience, I've never used more than one sub. I'm currently using a 20 year-old B&W ASW650 (lit says 12 inch but more 10-11 inch) in my smaller room (12 X 13). Listened to Joni Mitchell's intro to "Cotton Avenue" recently and Jaco's bass was "all there" which is good enough for me.
Good luck with you project!
