Do you have the 140-15D?

No, I am using the more common 70-20xr.

I am pretty sure that tweeter, even mounted in a waveguide, will not go low enough for a 2-way.

Looks like 2 way isn't a problem.

A TD12M loses directivity above 1,200hz.

Why are you considering such a high efficient woofer to use with this less efficient tweeter? Won't that cause some issues with regards to the crossover design? I would use a pair of ScanSpeak Rev's or Illuminators as they will easily play to 1,800hz and have excellent sound quality and be a better match sensitivity wise, assuming that you go with a passive crossover as using an active crossover might make this a non-issue!
If it were me, I would make this build a 3-way active using a nice mid from the likes of Seas, ScanSpeak, or possibly Moral, or even a planner mid such as the BG Neo10 or Neo8! A 3-way setup using the Neo10 from 400hz to 2,000hz with the RAAL covering everything above that would be freaking awesome! You could then do a pair of W18's or a pair of ER18's for the low end!

The RAAL 140-15D is 95db sensitive. Put a waveguide on it and it will be at least 97DB sensitivity. A TD12M is 96.5db sensitivity. Looks like a good match to me, if the RAAL could go low enough. I know the Beyma TPL-150H can go low enough and it has enough sensitivity to be matched with a pair of TD12M's. Only problem with matching a pair of TD12M's with the TPL-150H is my TD12M's are 8 ohm versions. I guess I could use my MiniDSP10x10HD as an active crossover with the pair of TD12M's at 4 ohm and the TPL-150H at 8 ohm.

Mixing 4 and 8 ohm is not a problem with passive.
Even on a wide baffle, usually there's some low frequency loss that'll reduce the final sensitivity around 3db or so.

I think I will go ahead and order three TD12M's in 8 ohm version and see about getting the TPL-150H drivers, since I know those will go low enough. Need to go MTM to get the tweeter at the right height. Will baffle wall mount these. What would you suggest for box volume sealed and ported. Will be used with multiple subs. Just need to get below 80Hz.

Two TD12M's per speaker in a MTM configuration. If only need .6CF per driver for 80hz sealed, then I would shoot for 60HZ f3

The TD12M's ordered, so dual TD12M's it is.

This build is going to be really something. I'll be following along. I'd love the opportunity to assist. I know Face has some good experience with AE drivers and also think he's used the TPL150. If not, he's used other ribbons and such.

A little different, it has an ambience tweeter mounted on the back.

Not looking forward to the tear down of my front wall. Just did this earlier this year. Will have to remove masking system, screen and sound panels. Then will have to remove the block out I have in the wall for the center speaker. Install a larger block out, then build baffle on front wall. Between that and the speakers will be a lot of work, but looking forward to the finished product.
