The JBL Professional CWT128 is a 450W 2 x 8-inch passive 2-way installation loudspeaker designed to deliver exceptional sound clarity, wide coverage, and compact versatility. With its innovative Crossfired Waveguide Technology, the CWT128 provides seamless 160° horizontal by 60° vertical coverage, making it ideal for spaces requiring consistent and broad sound dispersion without compromising architectural aesthetics. The loudspeaker's compact footprint allows for installation in environments where space or visual impact is a concern, offering a superior alternative to using two splayed loudspeakers.
Equipped with dual 8-inch JBL SFG (Symmetrical Field Geometry) low-frequency drivers, each with 2.5-inch copper-clad aluminum voice coils and copper-clad pole pieces, the CWT128 minimizes distortion while ensuring powerful, accurate bass reproduction. For high frequencies, dual 1-inch exit, 1.5-inch diaphragm 2408H-1 compression drivers provide smooth and detailed sound. The advanced passive crossover network ensures optimal performance, with a crossover point set at 1.5 kHz. The loudspeaker supports distributed audio systems with an integrated 70/100V transformer offering taps of 110W, 55W, and 28W (70V only), and includes an 8-ohm bypass for direct audio connections. Its high sensitivity of 94 dB SPL at 1W/1m and a maximum SPL of 129 dB deliver impactful sound suitable for demanding applications.
Built for durability and versatility, the CWT128 features a rugged enclosure constructed from 12 mm and 15 mm exterior-grade multi-ply hardwood, coated in JBL's textured DuraFlex finish for long-term durability. A heavy-duty, powder-coated 16-gauge steel grille with acoustically transparent foam backing protects the drivers while maintaining sleek aesthetics. Multiple mounting options are available, including four M10 suspension points and four M8 points compatible with the MultiMount MM-120-BT bracket. Compact dimensions of 31.94 x 12.22 x 11.84 inches and a weight of 40.9 lbs make it easy to integrate into a variety of installations, from houses of worship to commercial venues.
