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. Its highest-quality heavy-duty drive components use 104-ounce magnets and 3” voice coils as well as proprietary speaker motor assemblies to deliver high sensitivity and advanced power handling capabilities.

Ideal for clubs, theatre's, auditoriums, churches, and performance halls the plywood construction tuned port enclosure applies CNC fabrication techniques for uniform tolerances and build reliability.
