Looks like the Linkwitz Phoenix except the woofers aren't aligned front-to-back and wired out of phase. His comments about the compression in the space between the drivers being different than the Phoenix are just plain wrong, the Phoenix is push-push too.... Paul (Don Diego) is using a pair of the Phoenix subs that I built years ago with his Acoustat 2+2s.

To me it looks valid and I find it interesting that the free air resonance is lowered. Of course as with all things audio you won't know until you build them.

I got eight woofers salvaged from the Amazings to play with

They're all just variations on SLOBs, they ought to work fine. It's really mostly a question of the size/shape that works for you.
