I was given a pair of Mach One's today. One is minus the woofer the other has some cone damage and needs foaming. When I was a kid I drooled over the pair a family member had. The midrange and and tweeter are both horns. (If I recall right, these were rather pricey for the day about $750 for a pair in 1980) I want a quality 15" that isn't going to cost me a fortune. Any suggestions.
