Hi there, i am about to order the rest of Axiom speaker to built a 5.1 home theater set. So far i have the VP150 center, M3 V2 front and EP350 sub. Due to space and wall possibility, my rear speaker will be set at 90degree from listing positon. I cant place them 2-3 feet behind because i have door and the only posibility could be at 6 feet behind (too far i guess).
So i wonder if i should go with another pair of M3 for rear or QS8 would be a better choice for surround ?
Take note it is only for movies.
Thx for advise
