Crossfired Waveguide Technology (CWT)

At the heart of the CWT128 is the CWT Waveguide featuring a wide coverage pattern designed to provide seamless horizontal coverage across a full 160°. Based on JBL patented technology, the CWT Waveguide is essentially split in half and loaded with two compression drivers facing in different directions.


Proven Dual 2408H-1 Compression Drivers

High frequencies are handled by dual 2408H-1 1" exit, 1.5" diaphragm neodymium compression drivers that deliver higher power levels with lower distortion, better coverage and lighter weight. These proven JBL drivers are renowned for their high power handling and smooth response.

High Performance 8" JBL SFG™ Low Frequency Drivers

Low frequencies are handled by 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. The SFG LF drivers combine smooth response, extended low frequency bandwidth, and extremely low distortion. Delivering an optimum balance of efficiency and bass response, they perfectly complement the CWT Technology.
