Model #: KI-215-SMA-II-Raw Birch
At a Glance
The KI-215-SMA-II trapezoidal array-capable (sixteen built-in 3/8” 16-thread fly points) subwoofer perfectly complements Klipsch’s high power full- range loudspeaker systems. The KI-215-SMA-II’s enclosure dimensions and rigging configuration are identical to the KI-362-SMA-II full-range professional loudspeaker system, making it an ideal match when using an external, active two-way crossover.
