I'm thinking of using one of these for surround and height channels for a 5.2.4 system. Seems like the A2+ has potential to be better with larger mid/woofer, more cabinet volume and sealed enclosure. Plan for now is to use monolith 365T, 365C and 2 12 thx subs for the 3.2 part. I haven't seen measurements of the A2+ anywhere.
