I assume you are 7.1 or 7.2 right now? What is your Atmos goal, 5.1.4 or 7.1.2 or 7.1.4?

Can’t tell if you are looking to buy additional m5 in-wall for atmos or to repurpose what you have?

If you are keeping what you have for surrounds and looking to purchase additional speakers for Atmos, I suspect M5 in-wall might be a little beefier than what you need for overheads.

Whoops, this should work:

I have a 7.1 system now, M80HP's, VP180HP & M5HP's for rear and will be trading-up my side QS10's for on-wall M5HP's. Will be powered by Denon X8500H using out board ATI amp for main 5 channels.

I am looking do 7.1.4. I think 6 overhead might be too much. My room has one row of 3 seats and is 19' x 13' with 8' flat ceiling. Dolby recommends ceiling speakers be placed at 45 degrees in front and behind listener. That puts them at 4'6" which is a 9 foot spread.

Dolby does indicate there is some wiggle room on this spacing but I'm still concerned about the dispersion. As mentioned there is no easy way to tilt the mounting of an in-wall (ceiling speaker). I really don't want to mount any kind of box speaker on my ceiling. Wife has her limits, this is our living room.

You have the M5s so you're familiar with their excellent off-axis characteristics. The tweeter is quite linear to about 60 degrees and the mid to about 45 degrees. Beyond that, they don't sound bad but their character does change.

If you place them with their mids 4 feet ahead of your MLP, assuming your ears are about 3 feet off the floor, you'll be within the range of the above angles.

It appears the X8500H is the one receiver to rule them all!

First off thanks for the info on the M5's dispersion. So if I were to go with the M5's or M3's (in-wall style) in-ceiling how would I place them? Horizontal with the tweeter furthest or closest from MLP or horizontal, tweeter in or outside?

Sitting in the center seat the angle to the in-ceiling speakers is shallower as the distance is further than the end seats. My ears are 3'6" from the floor.

Thanks again for your thoughts.

Yeah can't wait

I don't have ATMOS but if I did, I'd experiment with orientations like the ones I show at the link below.

On the subject of the aimable tweeter, the M3 in-ceiling does have an aimable tweeter. It is also quite unique how it works because it is a gimbal. The tweeter itself pivots in one direction and the ring around it pivots in the other allowing you to point it in any direction. The gimbal avoids the problem of the tweeter pivoting in a socket which results in the edge of the socket interfering with the tweeter's response.

Thank you Ian! A few follow-up questions.

1) With the aimable tweeter, does the orientation of the speaker matter when in the ceiling or just slap it in the ceiling and just adjust from there?

2) What screws specifically do I adjust...there are many!
