Ya, fair enough. Got a little derailed. If you have the in-ceiling m3’s like you say in your original post, can’t you just look and see if it is amiable?


I wasn't about to go start messing around unscrewing my new speakers!

You can't just take off the grills and simply position the tweeter to the angle you want?

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.



I got a response from Ian saying to place the tweeters closest to the listeners. This was in response to me stating the speakers would be mounted lengthwise (front to back of room). Though I would think the answer would be the same regardless of speaker orientation.

I didn't know the M3 in ceiling had a pointable tweeter. Given this, I may go with them instead.

I can't imagine one would notice much of a difference between the 2 in Atmos duty and having the aimable tweeter will give me a little more 'tweaking' ability.

Hi hhiggins,

It is just a slap it in and adjust to how you want it as the gimbal goes in all directions.

The screws are all factory set, you do not need to touch them. You can just push on the tweeter and/or the ring to point the tweeter in the desired direction.

Thank you Sir! Glad I didn’t mess around with the screws. Cheers!

Ian innovates 18 hours a day and when he's sleeping, he's still innovating in his dreams. Somewhere in between all that, he makes time for us on these boards!

If I assume that the post your referring to is mine (I decided not to use the M3c for my Atmos ceiling because of concerns with imaging). My thinking:

Atmos is an object placement format. The movies sound engineer states “this object is at this point in 3D space and here’s it’s audio track”. Given that infomation each play back system (yours, mine, your local movie theater, etc) figures out how to get it there by using its unique speaker layout and locations. How close to the exact location will depend partially on how well those speakers image.

That said, at the moment Ian is probably right ... most of the time it’s just an overall effect, the exact placement does not matter. But the power of Atmos is when is does matter and I suspect as time goes on it will matter more and more as engineers embrace this format.

So if Ian told you the M3c's don't image well do to their recessed driver are you going to use the in-wall M3's?

I'm still trying to figure this out for myself.

Here are a few links you might be interested in. The first link talks about how important it is to have wide dispersion in-ceiling speakers.

thanks for the articles. Im assuming the M3 onWalls and M3 inWalls are very close in their sound characteristics. It would be interesting to see a set of X & Y axial graphs at a few frequencies

Thinking of using onWalls but have not rule out inWalls ... for me the decision between the 2 has nothing to do with reproduction but more with trying to meet Massachusetts electrical code and optimizing sound proofing. These conflict a bit And I have not completely sorted out all the issues
