Hi, I have a pair of walnut Libra c53 cabinets loaded with LE14A woofers + LE175 horns + LX10 crossovers. Doing research online this seems to be the S1 component system loaded into the C53's. Is this from the 1960s? All works fine and the components have close matching serial numbers pair to pair. And is there a bluebook or good valuation site for these?
thanks, Rick
