They look good. Would be nice to know which drivers are used or derived from (as it would with cabs from almost every outfit
Because of this, I really can't see buying anything other than boxes from makers who do
reveal the drivers used. Or, of course, building a custom where you specify the drivers. Up front & above board...that's what I believe in.
If someone hears a box w/unknown drivers in person, though, & likes it, & it's a good value (new vs. new or used vs. used) to cabs that have quality known drivers, then each guy can go on with his bad self. That's my take anyway.
