BASSBOSS VS21 21" Powered Subwoofer

With its massive 21" driver, the VS21 active subwoofer promises to redefine your idea of low-end reinforcement, pushing bass from simply an auditory experience into a physical experience. Its onboard Class-D amplifier with built-in DSP drives the VS21 with 2,400W of sustained output, allowing it to comfortably reach down to 27Hz and sustain a 132 dB SPL without breaking a sweat. The VS21 is a vented short-horn hybrid subwoofer, which is rear-loaded into a large acoustical volume and tuned to a low frequency, and front-loaded onto a short horn. The vented enclosure section provides extended low-frequency performance and the horn section provides increased upper frequency sensitivity and improved transient response.

BASSBOSS was born out of a passion for ultra-deep low-end, and a belief that tight, clean, accurate bass is the foundation of great sound. Each BASSBOSS product is a mindfully engineered, painstakingly tuned, completely integrated audio system, intended to seamlessly pair with other BASSBOSS products. BASSBOSS speakers are designed, built and hand-assembled in Austin, Texas, using only premium components. Like its siblings in the BASSBOSS lineup, the VS21 powered subwoofer is optimized for full-power usage. That is to say, it's intended to be pushed hard and abused, gig after gig. So, don't hold back—crank it up.

BASSBOSS uses only continuous RMS power ratings because you’re not going to be using your sub in millisecond bursts. For subwoofer applications, peak and burst power ratings are largely irrelevant. 2,400W of continuous power with integrated, comprehensive DSP ensures the amp isn’t the limiting factor in the output of low frequencies, and prevents overheating issues and virtually eliminates the damage that clipping an underpowered amp can cause. BASSBOSS specs reflect what the products will achieve, consistently, in the real world—since the real world is where you’ll be using your gear.

Built to withstand the rigors of repeated gigging, the VS21 powered subwoofer is constructed from 18 mm Baltic Birch plywood, using dado joints, screws and advanced composite adhesives. Stainless steel bolts are used to secure the driver, amplifier and pole sockets. The cabinet is finished in an extremely rugged, black polyurethane coating. The VS21's driver is protected by a black powder-coated, perforated steel grill, and the amp is recessed into the back of the cabinet for protection from damage.

Complementing the SSP218's virtually indestructible design is a 21" driver that is also built to take a beating. The woofer cone is waterproofed to protect it from accidental exposure to moisture, such as rain or spilled beverages. The added benefit of a waterproof cone is that you can clean the driver with a damp cloth in the event it becomes soiled.
