I have owned a SX 850 and currently have a SX 950 and SX 1250 and I enjoy their sound very much. I do run a Pioneer SG 9500 eq with them. If the price is right you should enjoy. My units have had a full recap including the tuner board.
I picked these up yesterday! They are in very good shape and sound nice with my SX1250. I am glad I responded to this ad, because who doesn't need another pair of speakers?
