There are a few other candidates, but you'll have to model these for yourself for the moment. I have to go now. Here they are in no particular order:
GOLDWOOD GW-208/8 8" OEM WOOFER 8 OHM
GOLDWOOD GW-8028 8" BUTYL SURROUND WOOFER
GOLDWOOD GW-206/8 6-1/2" OEM WOOFER 8 OHM
GOLDWOOD GW-6028 6-1/2" BUTYL SURROUND WOOFER
There are also two 'Buy-out' woofers that would work. These are available for a limited time only, but the prices are very low. These are:
8" SHIELDED WOOFER 16 OHM
6-1/2" SHIELDED POLY WOOFER 12 OHM
Have fun playing.
Enjoy,
Deon

Deon, thanks for modeling these.
Also doing two woofer arrays breaks the guidelines for the Line Arrays driver to driver distances.
I originally though about symmetry, but then after reading and studying, I settled on a single LA.
I do plan to make this a sealed cabinet, as I’m looking for smooth response down to 60hz (even though I plan to cross over at 85). Power is not a concern.
Open baffle or dipole is also out. My big Monoliths are dipoles and still have issues (with SPL) down around 130Hz.
From the looks of these graphs, none seem to have decent response at 85hz. I’m pretty sure six Extremis will deliver high SPL at 85 and at 450Hz.
The Extremis are now on order and should arrive here next week.
Cheers,

Build underway
I've received all the components and will start the build next week. The build process and discussion about design will be followed in a thread over on this Martin Logan Club Forum thread
