Caisson de basses actif V-TONE NBS-115 15

The V-TONE NBS-115 redefines portable bass reinforcement by integrating a 15-inch custom woofer and a 150W RMS Class AB amplifier into a rugged, carpet-covered cabinet. Unlike passive subwoofers that demand external power amps and crossovers, this active bass reflex enclosure delivers deep, punchy low-end straight from your mixer or preamp, making it a self-contained solution for stage and studio.

Highlights

• Built-in 150W RMS Class AB amplifier with 300W peak power
• 15-inch custom woofer in a bass reflex (ported) enclosure for extended low-frequency response
• Comprehensive EQ section: Volume, Bass, Mid, Treble, and Master Volume controls
• Flexible connectivity: XLR and 1/4" TRS inputs, plus XLR link output for daisy-chaining
• Rugged MDF construction with black carpet finish, perforated steel grille, and integrated side handles
• 35mm pole mount socket for elevated placement as a satellite sub
• Protection circuitry against overload and thermal stress

In daily use

On a cramped stage or in a project studio, the NBS-115 simplifies bass monitoring. Connect a bass preamp or mixer output to the XLR or TRS input, adjust the four-band EQ to shape your tone, and let the ported cabinet project tight, articulate lows. The link output lets you feed additional powered cabinets without a separate distribution amp. When used as a compact PA sub, the pole mount socket accepts a standard 35mm speaker pole, turning the NBS-115 into a foundation for a full-range top. The carpet finish resists scuffs, and the steel grille protects the woofer during transport.
