I am a total amateur at all things audio, so bear with me. About 30 yrs ago my grandfather gutted two walnut cabinets and turned them both into speakers using what I am told was the top of the line gear at the time. Recently I came across these and want to start using them. There is a single mono input on the back which I have hooked my iPod into using a stripped phono cord and a stereo adapter. The sound quality is great, but the volume is really low. When I hook a television up the same way, the sound is barely audible. My goal is to get these speakers working with a variety of inputs using phono or rca plugs. Obviously I need some specifics about manufacturer, tolerances, etc to get started, but it's a pain to pull these cabinets apart so I'd rather only have to do it once. What sorts of data should I collect from the speaker and is there any recommended reading or procedure for going about this project?
