I know this is an old thread but just picked up a pair of these KLH Model 363's myself and WOW!!! How are these not more well known???!!!! I have owned many a pair of incredible speakers, from Klipsch to Polk to DCM Timeframes, HPM 100's and so on and these things are incredible! Just plain Jane looking but I love classic designs anyway but still, nothing special looks wise, both in excellent condition, no chips, grills are flawless except for dust, badges still intact, all drivers are well sealed, they actually look like they weren't played much or either kept in a nice environment. I'm really hoping someone out there can come up with the specs for these by now. Surely someone somewhere has come across an old owners manual or something by now? Anyone have an update to these? These should be way more coveted than many out there. Not real large but very well built and solid. Probably the best KLH speakers I've heard among the KLH line. Here's pics. Hope someone can post update on these for specs. Thanks!
