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!
