OK, I am still setting up my HT system. I mentioned that i have the 12" earthquake supernova and love it. I also mentioned my difficult 10x22 room, speakers firing the 10ft way. I have (2) exact matched JBL 150 subs, these came from my girlfriends home, they are about a year old, they are "decent" 10" 150/300 watt powered subs, cost about 300.00/350.00 ea. new. with such a long room would it make sense to (stack) the twin JBL's at one end, and put the supernova at the other, then try to tweak them in, or is 3 subs from 2 different menufactuers just going to cause more problems. I don't have a room that can support the JBL's now, they are just sitting there. I quess my question is: I have heard that bass is bass, kinda, and not as critical to be paralelled as other types of speakers, any suggestions on other placement in a 10x22 room, Thanks Jon
