These are extremely rare CAT custom made from a company in California that designs speakers for home theater, custom sound rooms, yacht's, etc. called California Audio Technology. These are called Balboa's. They claim they are the worlds best speaker designer with their top model at $500,000 a pair. This simple 2-way monitor is spectacular to hear, very clear and detailed. Hardly ever available and made for a midsize room. Price for these has actually gone up 30% than the list price shown. THIS IS A DEMO PAIR, so very lightly used. Paypal add 3% please! These were used with Classe gear and placed with this system for size reference. Make offer, an absolute steal at this price!!!!!
