Reference 3A Grand Veena Placement

Can these speakers be placed near the back wall?
Yes and no. Yes, they will play. No, you won't be getting your money's worth. Some of this is room dependent, but speakers need breathing room, without it, it is impossible to capture the size of the venue. In fact they often need to be WELL out into the room. A serious WAF issue.

I recently moved my Magnepan 3.5Rs out from 6 ft to 8 ft (BIG ROOM!) the improvements were phenomenal
