I bought this subwoofer about 9 years ago for home theater. Excellent condition -- A little dirty, no real visible scratches. Works fine, but I wanted to upgrade to a better one (I got a Definitive Technology SuperCube) and also have auto power-on. I must be getting lazy in my old age. manual and brochure: Search Google for "mirage ps-12-90 subwoofer brochure" There was a recent Ebay auction where a PS-10-90 was bid up to $137.50 but did not meet the reserve price: Search Ebay for "5716510612" and it will find that item by number. Asking price: $100 obo. This is for San Francisco area pickup. I don't think I'm interested in shipping, because it's big & heavy and I have no experience selling and shipping such items. If interested, send me email at [email protected].
