These are in really nice shape. Cabinets have sharp corners and no blemishes as far as I can tell. Grills have a couple pin holes, a small stain but overall present very nicely. These sound great, all drivers excellent(albeit a little dusty) except for 1 woofer that has a small tear on surround, and will need to be refoamed. These can be bi-wired / bi-amped.
