Slight update: I made a version with a space for horn and compression driver, the cutout I drew is for 18Sound 1,4 to 2 inch XR series horns but there is enough space for example JBL 2380 series of horns.

Update from other thread:

Here is our current version of MT121 with cutout for XR2064 horn and with 157mm of depth available for 12" driver. Also included is some sort of mockup of connector panel with cutouts for 4 Neutrik STX series 4 and 8 pole Speakon connectors. Even though XR2064 is made out of aluminium, we are going to also build a support panel for compression driver.

Hello! The driver I want to put inside the single MT121 (without the horn) is 155 in total depth. How can I modify the back chamber to fit it in? How much space do I need between the magnet and the backdoor? Right now there is 145 MM from the baffle to the backdoor.

The later 2 way version in 15 mm with CD top, isn't this MT121 40X25 degree dispersion? So I would need 4 per side for 160 degree splay?  I am thinking JBL 2386 2" horn with a JBL 2450 CD? 

Thanks for the input, 12PE32 is what I am going to use.



BASS, how low can you go!

Lots of pics of MT121 has been removed or gone also the zip file in previous discuss , I need more information(like flare angles) before I start it.
