All this talk of an M2 center channel has me wanting to try that out. I am curious if in my setup an on/in wall M2 would sound better than my currently installed on/in wall VP150. For the 'relatively' low cost of a single on/in wall M2 I might just be tempted to try it out.
It might look a bit funny but it will fit with some minor drywall work & repair. Thoughts or recommendations anyone?
