3 OA 12s would get pretty nasty. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif Also they sound GREAT doing it. I agree about the cost versus performance...If there is a woofer out there that will touch the OA in SPL and sound good doing it at that price point ,point me to them, I'd like to try a few myself! Lol
