I'm due to order some AVI Neutron 5's when monies get paid in to the bank very shortly, but I've come across a very good ex-dem deal on these speakers. I've only ever read and researched excellence on these speakers, but I'm a little concerned about rear wall placement as it seems they may need a bit of room. Maximum I have would be 12"so any opinions as if this would be sufficient? I would be buying "blind" but quite happy to take the risk as long as they don't need more than a foot!
