I have for sale a rare set of speakers that I picked up years ago. I can easily hook them up for a demo. The upper cabinets are separate from the lower for time alignment purposes. The surrounds are rubber on the woofers and doped fabric on the 4 in so you should not ever have to replace the surrounds of these speakers. I have provided some technical information below.
