JBL Professional VTX-B15 - Compact 15" Arrayable Subwoofer with SlipStream Ports, Integrated Rigging, and IP55 Rating

The JBL Professional VTX-B15 is a 15" arrayable subwoofer that extends the bass extension of full-range VTX systems in a compact, agile form factor. At its heart is the new JBL 2285H woofer with dual-voice, dual-gap Differential Drive technology, neodymium magnets, and a carbon fiber-based cone , capable of delivering low distortion, high linearity, and reduced thermal compression. Double-flared SlipStream™ ports reduce turbulence and port noise for cleaner, high-end bass.

The B15 incorporates an integrated suspension system with captive plates and quick-release pins that allows for flown or stacked arrays , in omni or cardioid mode, and is width and hardware compatible with the VTX A6 for mixed (flown or ground-stack ) configurations. Front and rear panel connectivity (4 × NL4) simplifies wiring, with 1± / 2± selection from the panel to optimize channel usage. Additionally, its tour-grade birch plywood construction with a DuraFlex finish , 1.5mm steel grille , and IP55 sealing (with MIL-STD-810 validations and UV resistance) guarantee reliability on tour and in permanent installations.

Main features

Product benefits

• Powerful bass in a compact format: deep, controlled response with a smaller footprint and weight than 18" solutions.
• Fast and secure deployment: rigging with quick-release pins and self-locking angles for quiet and precise assembly.
• Clean wiring; rear and front connectors plus a pin selector for cardioid blocks with simple layouts.
• Coherent ecosystem: integration with VTX A6 and availability of accessories (mini frame, suspension, ground-stack , transport) to adapt to each project.

Use cases

• Touring and rental applications requiring compact, arrayable, cardioid subwoofers.
• Theaters, auditoriums, churches , and corporate events seeking high SPL with pattern control.
• Mixed systems with A6 VTX in flown or stacked configurations.

Frequently Asked Questions

Can the B15 be flown and combined with the A6? Yes, it shares the same width and hardware as the A6 and can be flown or stacked, even in mixed configurations.

How do you make it cardioid? Orient the cabinets according to the layout and use the cardioid preset ; take advantage of the NL4 front/rear and the 1±/2± selector for clean wiring.

What amplification does JBL recommend? Crown iTech 4x3500HD and 9000HD (up to 2 speakers/channel) or 12000HD (up to 3 speakers/channel).

How many subwoofers can I stack? The rigging system supports arrays of up to 15 B15s , depending on accessories and design.
