Exceptional Opportunity! Hand-built by Albert Von Schweikert himself. As gift of friendship, he selected all drivers for best quality and matched them (left to right) within one tenth of a decibel throughout their range and matched internal damping within three tenths of an ounce. These exact tolerances result in unrivaled stereo imaging and revelation of detail. Add just posted on the Gon and Circle. I am going for the new 55's with a lump in my heart hoping my babies get an appreciative home, and excitement for the latest and greatest.
