I have wanted to do this for a while, but do not have the design skill. Anybody interested in designing a speaker with these components:
RAAL 140-15D: http://www.madisoundspeakerstore.com/ribbon-tweeters/raal-original-140-15d-ribbon-tweeter-with-optional-amorphous-core/
RAAL fiberglass wavew guide: http://www.diysoundgroup.com/plastic-seos-12/seosraal.html
AE's TD12M
Only requirement that I have is no more than 12" deep out to out on the cabinet.
5/15/14
Not going with RAAL. Going to use Beyma TPL-150H.
I think I have decided on size. I can make the exterior 15" wide x 11.5" deep and 44.5" high. It would be an odd MMT. The drivers will be tightly spaced in the middle of the box. The woofers will be above the tweeter, so that the center of the tweeter will be at ear height.
4.95" top of cabinet to TD12M
12.5" for TD12M
0.25" space between the two TD12M's
12.5" for TD12M
0.25" space between TD12M and TPL-150H
9.05" for TPL-150H
5" between TPL-150H and bottom of speaker cabinet
