I currently have M5HP in-walls on either side of my wall-mounted 75" TV. I'm debating swapping the TV for an 85", which would just fit between the two M5's. I slid the existing TV over to simulate how an 85" would sit near the M5. The face of the TV is 3.5" from the wall plane. Would having the TV so close to the M5's hamper their ability to produce the great sound that I enjoy from them today?

It would add a reflection point to the speaker. Why dont you test it with a couple of pieces of 2x4 placed against the wall. It would give you about the same profile at the TV will.

Not a bad idea, thanks!

It won't audibly affect the Listening Window Curve but it will affect the Early Reflections Curve. Your image width, stability and timber may all be audibly affected. It would be interesting to see graphs after you put the 2x4s in that Matt suggested.

I put the question to Ian as well, and 'less than ideal' is what he said. Looking like I may need to swap for on-walls (or bookshelves if I really want to test WAF).

If you do bookshelves, do not move them into the room. You will hear a deep soundstage the likes of you have never before witnessed as if the M5s are projecting images to the back. You will kick yourself when you have to butt them up against your front wall.

Does putting them on full metal brackets count as butting them up against the wall? That's really the only spot I have to put them.

FMBs are the same as butting them up. To create what I described, the backs have to be at least 3 feet away.

This is 2 feet at my friend's. I also moved her couch into the room (not shown). She can't ever go back to butting them up against the wall.
