I found these early Klipsch KP-650 brochures. Not sure what the story is on them but they look like a mock up. I've actually heard the modular KP650 and it is very good. I was surprised at how hifi they sounded for pro speakers. Would be a fun pair of speakers for the living room. WAF meter would be pegged.
