We'll subs are in one big standing enclosure divided in the middle. It is currently in the front left corner of the room, I was wanting to build separate cabs and place one on the other side of the screen. Don't really know how this will sound because about 6 feet from there is a hallway. I had two 12's set up this way and did not like how they sounded. They were only being pushed 150 watts each so that's probably why they sounded like crap. Would it be worth me building new cabs for the 18's to see how they react placed this way or do I just leave it alone since I have seemed to find the sweet spot in my room???
