The JBL VTX B28 is a flagship dual 18-inch subwoofer engineered to deliver powerful, articulate low frequency performance for the most demanding live productions. Designed to complement JBL's VTX A-Series line arrays, the B28 provides exceptional output, extended low end response, and precise bass reproduction for concerts, festivals, corporate events, arenas, and large scale touring productions. Its advanced enclosure design and next generation Differential Drive® transducers produce deep, impactful bass while maintaining outstanding clarity and musicality. 

Featuring dual JBL 2288H-M 18-inch woofers with fourth generation Differential Drive technology, the VTX B28 delivers impressive efficiency, reduced power compression, and exceptional transient response. The enclosure can be deployed in either omnidirectional or cardioid configurations, allowing system designers to optimize low frequency coverage and significantly reduce unwanted rear stage energy. 

Built for the rigors of touring, the B28 incorporates integrated suspension hardware, durable birch plywood construction, and a rugged DuraFlex finish. Whether flown alongside VTX arrays or ground stacked in large subwoofer configurations, the B28 delivers the power, consistency, and reliability required for world class sound reinforcement.
