It is composed of a sound column consisting of 8 x 2.3 ” and a bandpass subwoofer box with a 12” long-stroke subwoofer unit.
The unique phase plug design can greatly widen the radiation angle without damaging the frequency response of the units. The coverage angle reaches an astonishing 140 degrees. Even people on the side of the speaker can clearly hear the flat sound signal.
It has a built-in two-channel mixing circuit and the volume can be adjusted independently.
