To add spaciousness, one of its two piezo electric tweeters faces the rear. These specially developed, remarkably clean sounding tweeters, unlike other piezo electric devices, use no horns, but act as direct radiators. To prevent interference from the woofers, a new 10 centimetre midrange driver is sealed in its own sub enclosure. To provide excellent transient response in the midbass range, a 25 centimetre woofer utilizes an unusual low mass radiating element. To couple bass output to the room, a 25 centimetre subwoofer faces downward, near the floor. Radiating area of the two woofers, configured in what audio engineers call a dual driver staggered resonance system, is 60% greater than that of a single larger 30 centimetre woofer. Column II can deliver plenty of bass and plenty of power, without the roughness and midrange peaks typical of many high efficiency speakers.
