Upgrading home theater. Currently have on wall m22's and vp150 center on wall, qs8 surrounds and EP 500. My initial thought was to replace with m5hp and vp160 mini on wall. Problem is I'd like to go to 77" tv, and the M5hp's will just barely fit into the space, and M3 on walls will fit a little easier. I'm keeping the EP500, and I could make the M5hp's fit easier, but that will require some carpentry work. Would the M5hp's be worth it? I could also go to 65" tv and the M5's would fit better. Room is 15x14'.
