Severely underpowered.

Those are good cabs but not worth the asking price. Half that would be about right.
When KMD amps came out they failed left and right out of the box. We called 'em Kolossal Mountains of Dung.
The only amps of theirs I ever saw were three or four 15" combo amps for keyboard and bass. They were very pricey new, same as 90's Trace Elliot, and the ones I saw hit the redneck bar circuit and AFAIK are still going strong today. They didn't really have their own sound; they were just solid combo's that were decently loud and versatile. They had a ton more natural low end than most combo's I've ever messed with, so I assumed that all their bass speakers would be of equal quality.
