They're cabs built here in Italy by a company with the same name and let me tell you: they look nice, and they sound GREAT!
No unwanted reverberation inside (yes, the rooms are tunable at will), high sound damping on the outside! You'll love one of theese rooms.
Just for honesty, I don't get a dime for maketing, it's just passion!

Here's a photo of the center where I work here in Livorno (they added the Boxy logo in CG for commercials).
