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 exponential 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 supplementing large VTX systems. It's never been easier to deliver impactful, VTX-quality sound at any scale.
KEY MESSAGES|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 creates a rigid diaphragm, significantly reducing mass and cone breakup distortion. The result is a robust 15-inch woofer with an impressive peak-to-peak maximum excursion that rivals 18-inch designs.
CONTROLLABLE COVERAGE
The B15 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. 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 compatible, and arrays of up to 15 subwoofers can be created.
