I'm guessing that if putting a hole in your wall isn't an issue, the on/in hybrid would be the better sounding option?
I'll also see if keeping my current M60's mated with an in/on-wall VP150 may work (aesthetically).
Lot's of options, just want to be sure I pick the best one, as knocking holes in walls and then
realizing that wasn't the best choice would suck.
If I get a chance I'll take a photo of the space as it is, and let you guys give me your ideas.
