Re: Are vht cabinets reliable
The thing you want to look for, IMO, is a plywood cab, not MDF. I don't think the MDF holds up well "...on the road". So if you are taking out of the house to gig, get a plywood cab.
The problem is, with many manufacturer's, you have to do a bit of reading between the lines in their catalog, so if it doesn't SAY specifically that "...this cab is plywood," or "...all our cabs are plywood," (like Mesas), they will probably be some form of pressed sawdust, and not road-worthy.
Good luck.
