The JBL Crossfired Waveguide Technology CWT128 is a full-range 2-way loudspeaker system designed to provide extremely wide-angle coverage with maximum bandwidth and SPL in a compact package. The unique wide coverage pattern horn is designed to provide seamless coverage to 160° horizontally. Plus, the speaker's relatively small footprint makes the system ideal for nearly all architecturally sensitive environments, taking up about a third of the footprint of two speakers splayed side by side. And because one speaker can be used instead of two, installation costs can be lowered by reducing the number of cabinets, cabling, labor and more.

The CWT128 features dual 8" JBL SFG™ (Symmetrical Field Geometry) LF drivers, each with a copper clad aluminum edge-wound 2.5" voice coil and a copper clad pole piece that improves performance by reducing voice coil inductance and distortion. Additionally, the loudspeaker is equipped with dual 2408H-1 1" exit, 1.5" diaphragm compression drivers.

The rugged multiply hardwood enclosure is designed with multiple mounting options and is finished in JBL’s textured DuraFlex™ with a heavy duty powder coated steel grille. With an overall clean and rounded look, the CWT128 blends well with contemporary architectural spaces.
