Wall-shaking bass down to 24Hz and 2,400W continuous Class-D output.

With massive low-end reinforcement down to 24Hz, the DJ21S 21" powered sub is designed to provide extraordinarily deep, powerful bass that will you can feel in the floor and walls around it. Its compact form factor and output-to-price ratio are ideal for professional DJs, mobile performers and venue owners with space limitations who need maximum performance with a minimal footprint. The DJ21S offers plug-and-play simplicity, integrated DSP and Class-D amplification with a whopping 2,400W continuous output. The end result is a compact, portable and robust cabinet that crushes low notes most mass-produced subwoofers can't begin to reproduce.

For DJs and venues seeking extremely deep bass at very high levels, the DJ21S stands virtually unchallenged, boasting a massive 21" woofer. Audiences of today's popular dance music are addicted to bass; modern music features ultra-low frequencies well below the usual 40–50Hz range. To give your audience enough of the chest-vibrating bass they crave, you have few options. Other mobile subs don't come anywhere close to reproducing the low notes that the DJ21S cranks out. You'd have to buy four mass-produced subwoofers to come close to matching the abilities of the DJ21S, but you'd still fall short of hitting that low 24 Hz output.

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 products are designed, built and hand-assembled in Austin, Texas, using only premium components. Like its siblings in the BASSBOSS lineup, the DJ21S 18" 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 and feel the bass in your bones. Bass is good for you, your audience and your music.

Multiple proprietary protection technologies ensure that the DJ21S' huge 21" woofer remains within its excursion and thermal limits, so it won't break or burn like other subs. The DJ21S portable subwoofer reliably provides much higher levels of deep bass than mass-market subs, with plenty of headroom to keep up with the most enthusiastic, bass-hungry audience.

Built to withstand the rigors of repeated gigging, the DJ21S 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 DJ21S' 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 DJ21S' virtually indestructible design is a 21" driver that's 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.

A 2,400W RMS amplifier with integrated, comprehensive DSP forms the foundation of the DJ21S. 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 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.
