I like the concept: 4'' dia with M2 lens + 15'' low. Because IMHO proper 15 'sings right' below the CD part (I have 4429 at moment and I miss the authority of 15''.)

My project and 'philosophy' :
Why 'torture' same woofer with so much of octaves; 6-7 octaves simultaneously?
Why not to give lowest octaves to handle for the bigger boy like 2269, to what it's intended to. Cross 60...80Hz and below.
Did You even try to make two things simultaneously - drill a hole to wall with left hand and paint the wall with right hand same time? :-)
If 2216 is right now 'busy' with lowest part of male and suddenly comes in some a synthesized waves at 30hz, and thousands of another el.mgn.waves , simultaneusly...
Logic says, if cut of some part from low end, it 'releses' lot of energy and makes easyer to deal with higher waves.
When I started my first projects when I was 14, remember one rule - leave one woofer ca 3-4 octaves, if You can...
So: my discussion is: (not a argue),
why 2216+2216 is better than 2216+2269 ?
According what I have in mind:
- just want to pay attention, the listening room would be a'bit bigger than usual living room. It's a lounge area of production plant. Picture below.
Red line is planned thick curtains. Green arrows direction of sound (there is a quite damped wall behing the speakers). Orange area would covered with thick carpet.
Room is 4,5m high, 40 metres long...
The lounge (listening area) would be some 8x8 metres, covered with carped in the middle and surrounded with thick curtains.
I thing if I'm sitting in this geen circle, curatin behing me, basically like open air situation...
- With no exceptions I read everybody says, the M2 is good. Very good.
And JBL made a SUB18 too.
Why they made it?
- SUB18 is a box and a 2269. Right? If I take now a pair of M2 and and a pair of SUB18 (pair, because room is big) , like they are, originally, then everything is OK. Right?
But if I take lot of, for example, epoxy glue and connect M2 and sub18 together, the only difference I see : it's impossible to transport these two items separately, never, anymore :-)
So, how does it concern the sound?
Basically, my plan is 'glue' them together, simple as that!
And yes, 4'' dia instead D2.
