A compact sub-bass loudspeaker designed to provide high SPL low-end extension to SpekTrix line array loudspeakers. It is equipped with two powerful 18’ Kevlar cone drivers in a tuned and vented enclosure. The SpekTrix Sub features convertible cardioid technology. It can be arrayed conventionally (all enclosures facing the same way) or in front-back or front-back-front setups for true cardioid performance.

Four sets of captured, precision-machined aluminum rigging hardware are spring-loaded and retract into the body when not in use. Four NL8 connectors (two front, two back) enable easy cable loop-thru regardless of the cabinet orientation.
