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.
