VTX B15

Compact Arrayable 15" Subwoofer


The VTX B15 Compact Arrayable 15-inch Subwoofer extends the low-end performance of VTX full-range sound-reinforcement systems, including the new VTX A6 Subcompact Dual 6.5-inch Line Array Element. The B15 is a versatile solution for production companies, touring acts, rental houses, theatres, houses of worship or anyone who demands superior sound reinforcement when space is at a premium. Two models are available: the arrayable B15 and the B15G, which is designed without rigging hardware for ground-stacked applications.


The B15 joins the VTX B Series subwoofer family in harnessing VTX acoustic innovations such as SlipStream™ double-flared exponential ports and Differential Drive® dual-voicecoil woofer design; the subwoofer is based on JBL’s new 2285H 15-inch woofer, engineered for linearity, efficiency and excursion that rival 18-inch designs. The B15 has the same width and suspension hardware as the A6, allowing the two products to be combined in a range of flown and ground-stacked configurations. Design and operate systems with ease, using JBL’s suite of prediction and management tools.


Together with the A6, the B15 brings flagship VTX sound quality and performance to a new compact footprint, whether supporting small and midsize applications or supplementing large VTX systems. It’s never been easier to deliver impactful, VTX-quality sound at any scale.
