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.

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!
