Sorry for your bad luck Ken.

Having previously had a close look at my M22 XO's I would be surprised if your QS8 XO didn't survive; well as long as one of the driver cages didn't hit it upon impact.

I would be surprised if the cabinet has the crossover in it unless you asked for it. It would be another piece required to purchase seperately just like the drivers or the rear speaker connection plate, well the XO might come with the plate as it is glued onto it.
