Maybe some of you use some other brands than I do.

20+ year old B&W Signature Seven in walls have bad tweeters.

Sonance, Episode, most have a similar footprint. These have a 9-3/4 x 13-1/4" cutout and finished size is 11-1/4 x 14-3/4".

They are wider and not as tall as most I see. I can go bigger but not smaller.

These have 7" woofers. 8" based systems are still not quite wide enough.

Wonder if you've had to figure this out before. Thanks!
