Patrick Chu, creator and designer of the $80,000/pair, two-way, Mandarin Supreme loudspeaker, explained that the products’ name is a synthesis of two words: Loimin means "delightful understanding" and Chay means "ateliar or studio." The frequencies from 750Hz upwards are handled by a 1" tweeter loaded with a 19" horn comprised of alternating layers of cherry and oak wood. The bass, which is rated down to 22Hz, is handled by 10" and 12" woofers. This composite was by far the least active speaker material I've come across. Rapping it with my knuckles was like tapping on granite. The woofer enclosure was made of concrete with a cloth covering. I didn't ask about the loudspeaker's weight because I didn't want to know. The nominal impedance is 8 ohms, and the voltage sensitive a very high 92dB. Although I didn't audition any familiar reference recordings, the speaker had a dynamic sonic texture with a midrange emphasis.
