who cares if they are blown. the xovers and boxes in general are worth t he price of free. and they might be cheap to recone. I would gaffel the up and probably build some custom speakers
I have a pair of those speakers (12's tho iirc). They sound pretty good. They are ported, so they tend to get a bit punchy, but they do not lack for output (assume powered properly) and I enjoy how the tweets sound in them.
