Compression Driver and Cross-over not included
High power coaxial woofer for bass guitar and pro audio applications. A very capable stand-alone driver, the Kappalite™ KL3012CX has a threaded pole-piece so that a screw-on, 1” exit high frequency driver can be attached to form a coaxial set up. A screen type dust cap allows the output of the high frequency driver to pass through the center. A small, 60 degree conical horn is attached to the top of the pole-piece beneath the dust cap.
