JBL VTX-B28 Arrayable Dual-18-inch High Performance Subwoofer
The VTX B28 is JBL Professional’s next-generation dual 18-inch subwoofer, designed to complement the company’s flagship VTX full-range sound reinforcement systems, and capable of delivering uncompromised low-frequency performance, even for the most demanding shows on the planet. The B28 boasts JBL Differential Drive transducers, an exclusive port design, and the same industrial design found in JBL’s VTX A-Series products. It is equally ideal flown or ground stacked, in omnidirectional or cardioid configurations. Simple and fast rigging, a selection of accessories, and software support make the B28 an exceptional choice for rental, AV, and touring companies, as well as in high-end fixed installations.
A simple, integral, two-point rigging system allows flown arrays of up to 16 B28 enclosures. Three M20 pole mount attachments on the enclosure’s top can interface with standard Base Plate accessories for the A12, A8, and V20 systems to create ground stacked systems. B28 systems are powered exclusively by Crown I-Tech HD amplifiers and are fully integrated into JBL’s software ecosystem.
Key Features:
RIGGING SYSTEM
The B28 uses a simple and innovative two-point rigging system capable of suspending arrays of up to 16 B28 enclosures. Rigging components are hidden behind the two wooden side panels, and the two link bars are deployed by a spring-loaded mechanism. A unique, all-captive locking system secures cabinets together using a set of levers and sliding pins. The mechanism includes a safety lock to prevent unintentional release, and complies with all safety requirements. When B28 cabinets are ground stacked, the all-captive design keeps unused parts hidden and damped from rattling.
CONTROLLABLE COVERAGE
The B28 makes it simple to form omnidirectional or cardioid arrays. Speaker connectors are available on both front and rear panels, streamlining cable management in either configuration
SYSTEM SOLUTION
The VTX Series is a comprehensive family of hardware and software products and accessories that work together to facilitate the complete event workflow, from system design to transport home. Tools support tasks every step of the way.
PERFORMANCE

This driver leverages JBL’s patented, fourth-generation, Differential Drive technology to deliver maximum sensitivity and power handling in a light, compact design. The B28 is intended to provide, accurate very low frequency coverage adequate for the most demanding applications.
