For sale is a pair of M&K LCR-45's. I have the original boxes and manuals for the speakers. These were used as the rear surrounds in my smoke free theater. I have the SS-550 THX for my side surrounds, and after about 7 or 8 years of searching, I finally found another pair of SS-550's for the back surrounds to complete my 7 channel THX M&K system that I started in 1999, which is why I'm selling these. They are great little speakers and are great for surround use or as mains in a small theater. I believe the frequency response is 100hz-20khz. I bought them from a dealer that was no longer selling M&K due to the bankruptcy. They retailed for $$398/pr when I bought them and I am asking $175 for the pair. Buyer pays shipping and I'll take care of the Paypal fees. Thanks for looking.
