The VTX B15 Compact Arrayable 15-inch Subwoofer extends the low end performance of VTX full-range sound reinforcement systems,

including the VTX A6 Subcompact Dual 6.5-inch Line Array Element. The B15 is a versatile solution for production companies, touring

acts, rental houses, theaters, houses of worship, or anyone who demands superior sound reinforcement when space is at a premium.

The B15 joins the VTX B-Series subwoofer family in harnessing VTX acoustic innovations such as SlipStream™ double-flared expo-

nential ports and Differential Drive® dual voice coil woofer design. 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. Together with the A6, the B15 brings

flagship VTX sound quality and performance to a compact footprint, whether supporting small and midsize applications or supplement-

ing large VTX systems. It’s never been easier to deliver impactful, VTX-quality sound at any scale.

TRANSDUCER DESIGN

The B15 features a high performance 15-inch woofer based on the

patented Differential Drive technology, which uses a unique dual

voice coil, dual gap design. The extra surface area provided by the

dual four-inch voice coil design delivers better heat dissipation and

lower power compression than conventional single-coil designs.

The dual neodymium magnets are placed inside the coils, reducing

weight and improving magnetic efficiency. The outside of the woofer

is a unified cast aluminum frame, which acts as a large heat sink to

cool down the woofer. The ultra-robust carbon fiber-based cone cre-

ates a rigid diaphragm, significantly reducing mass and cone break-

up distortion. The result is a robust 15-inch woofer with an impres-

sive peak-to-peak maximum excursion that rivals 18-inch designs.

CONTROLLABLE COVERAGE

The B15 makes it simple to form omnidirectional or cardioid ar-

rays. Speaker connectors are available on both front and rear

panels, streamlining cable management in either configuration. A

switch on the rear input panel allows selecting between channel

one or two of the NL4 cable, minimizing cable requirements.

VTX A6 COMPATIBILITY

The B15 features a captive, spring-loaded mechanism for quick

deployment and quiet operation. The rigging system allows for

omnidirectional or cardioid configurations in small and large-scale

flown or ground-stacked arrays. The rigging system is compatible

with the A6, allowing B15 subwoofers to be suspended above A6

cabinets in flown arrays, or stacked on top of B15 using the A6

Base Plate accessory. All A6 suspension accessories are compat-

ible, and arrays of up to 15 subwoofers can be created.
