I don't know what their designs are exactly (the 2-15 I used looked like a sunn 2000S cab design), but in person, they sound boss. Loud guitar cabs. For bass, I would have wanted 2-4x15s. But, great quality build.
Corey, crank that shizznizzles!
I don't know what the design is really, vaguely Matamp/Electric-ish I guess. I might have him make me 4x15 eventually, I don't know how his bass cabs are. This guitar cab is really well built and loud as fvck though. Running my guitar through my Dunwich Cthulhu Fuzz Deluxe into Mr. Grumpy at noon into the Atlas is painfully loud.
