Assuming folded horns, even though folding horn enclosures do exist due to the fact that in order to get enough mouth area for strong low end reproduction, the size of the cab would need to be that of a van. Or a bus.
Fun to haul around if You can't take it apart for transporting
But, on the flipside, You'll get by with 1:10 th of the amplifier power to acchieve the same SPL.
I wouldn't call those particular CV's short horns, medium lenght or even long ones by todays standards.
1:10 (throat:lenght) and 1:3 (throat:mouth) or something like that judging by the drawings on-line.
I'd bet some of the BFM designs will do better, cheaper, and with modern drivers, but then again CV is one of those companies I don't particularily care about, based on the dreadful experiences with their "Disco" type direct radiating horn-look-alike "full range" cabs from the 80's.
