I don't have the O/96 but auditioned them a lot. My room is 15' x 13' with a large room opening in to a hallway. I've had a number of big floor standing speakers in there, but the O/96 is one of the few that had me wondering if they'd work in my room. They are pretty rich in the bass and definitely need space from the back wall.
Devore 0/96 and Room Size
I've really enjoyed the 0/96 every time I've heard them and there are a couple of used pairs for sale now. My biggest concern is that my room is 15 feet deep. I believe at least 8 feet is recommended so that the drivers blend and I don't want them closer than 3 or 4 feet from the wall behind, which only leaves 2 or 3 feet behind the listening chair. Would love to hear from owners about their experiences. Thanks.
