DJ21S Powered Subwoofer
Bringing the BOOM
WHY CHOOSE A DJ21S SUBWOOFER?
“Loco Mojo” = Crazy Movement!
With performance down to 24 Hz, the DJ21S will move the floor beneath you, along with everyone and everything in the room. For DJs and venues seeking extremely deep bass at very high levels, the DJ21S is the smallest, lightest and most cost-effective solution available. Suitable for the truly bass-insatiable, whose focus is on modern music that features frequencies well below the usual 40-50Hz range.
This extremely compact subwoofer weighs only 138 lbs and delivers output down to 24Hz (-3dB). The DJ21S is +2.5dB at 30 Hz while most subs are -10dB at 30 Hz.
That’s an equivalent output ratio of 4:1 at the lowest notes – and other mobile subs don’t get anywhere near this deep. Nothing else on the market of this size comes close – guaranteed. So you can buy four mass-market subs that cost more, weigh more, take up more space, and don’t blow people away… or use just one DJ21S.
Don't hold back!
BASSBOSS subs are optimized for full-power usage.
Multiple proprietary protection technologies ensure that the woofers remain within their excursion and thermal limits, so they don't break or burn like other subs. BASSBOSS provides much higher levels of deep bass than mass-market subs, reliably.
With plenty of headroom to keep up with the most enthusiastic crowd and not run out of bass.
So turn it up, and keep it up. BASS is good for you.
BASSBOSS not responsible for noise complaints.
The DJ21S cabinet is a vented enclosure that is tuned to optimize extremely low frequency output using a very large port. It was designed specifically to minimize materials cost and weight, and maximize efficiency.
Able to effortlessly reproduce the lowest notes in modern music. With frequency response down to 24 Hz, you can guarantee that you will hear, and feel, the deepest frequencies.
BASSBOSS cabinets are hand-built in the USA. They are constructed from 18mm Baltic Birch plywood, using dado joints, screws and advanced composite adhesives.
Created to stand up to intense usage. The cabinet is finished in an extremely rugged, black polyurethane coating. Drivers are protected by a black powdercoated, perforated steel grill, and the amp is recessed into the back of the cabinet for protection.
A 2400W RMS amplifier with integrated, comprehensive DSP is included. The amplifier is rated for RMS output using continuous sine wave signal.
This is not a Peak or Burst power rating. 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.
The amplifier is capable of delivering 2400W of continuous output. This ensures the amp isn’t the limiting factor in the output of low frequencies. Providing abundant power prevents overheating issues and virtually eliminates the damage that clipping a too-small amp can cause.
All that electrical power is converted into acoustical energy by a 21 inch neodymium motor woofer. This premium-quality driver features a split-wound 4.5 inch 4-layer copper-clad aluminum voice coil, and peak-to-peak excursion capability of up to 60 mm.
High-intensity Neodymium magnets are lighter and provide higher efficiency so the result is a lighter and louder cabinet. Split-wound coils produce a more linear force through the range of movement of the cone, which results in lower distortion and improved linearity at high output.
The woofer cones are waterproofed. BASSBOSS woofers can survive light rain, spilled drinks and dusty environments that may leave the drivers needing a thorough cleaning. Keep the amplifiers dry and party on!
The cones are waterproofed to protect them from possible, accidental exposure to moisture such as rain or spilled beverages. Waterproofed woofer cones also permit the cleaning of drivers that have been soiled in a dirty or dusty environment with the use of a damp cloth. Keep the amplifiers dry and party on!
Waterproofed cones in all products. Optional weatherized and weather resistant loudspeakers have the same acoustical performance as our standard options. If your system is likely to be exposed to rain, ask about IP rated amplification options. If you have need of a system for outdoor installation, ask about Weatherized products.
BASSBOSS subs can be connected directly to your mixer with nothing but signal cable in between. The built-in processing is comprehensive and yet minimal manipulation is applied to the signal. The processing includes only a high pass filter and a low-pass filter. There is no need for any EQ in the signal for the speaker to provide a broad, flat frequency response. A sophisticated limiter system protects the woofer from thermal and over-excursion damage.
Plug-and play with peace of mind. Multiple, sophisticated protection systems make the loudspeaker virtually indestructible. You can turn on and turn up, all night, without fear of over-driving to the point of damage.
BASSBOSS technical specs are based on measurements of continuous performance in normal usage. Other manufacturers may specify output based on calculations rather than measurements; measurements outside the operating bandwidth; or on ‘Burst’ or ‘Peak’ readings.
BASSBOSS specifications are conservative compared to most manufacturers. They reflect what the products will achieve, consistently, in the real world. Since the real world is where you’ll be using your gear.

This is the Magic Subwoofer I’ve been longing for!
My obsession with quality sound and extraordinarily physical bass began at a very young age, I dreamt that one day I would discover the “Magic Subwoofer.” I have always been the guy that has to reduce the bass because my subwoofers would begin to smell burnt after a few minutes of use, I’m talking about all the common mass market subs.
Right off the delivery truck, I had 3 DJ21S near full volume and the physical impact was True Lee breathtaking. Later on I turned it up to full volume, and after about 2 hours of pounding I noticed that there was no burnt voice coil smell at all. That’s a first. I also realized right away that I wasn’t craving more bass, I am finally satisfied. That’s also a first for me. The back of the amps were slightly warm to the touch. My old sub amps would have been hot. The depth is unreal. It sounds like “big concert bass”.
A wise man told me “Nothing is without a cost, you have to give to get.” This is for all the mobile DJ and one man show professionals who have the logical concern about transporting and loading gear of this caliber. Yes, it’s heavy. When comparing a 140 lbs BASSBOSS to a 90 lbs mass market sub, the increase in impact and performance hugely outweighs the increase in weight and this makes it totally worth gigging with the BASSBOSS.
A True SUBwoofer on a totally different level
BASSBOSS brings the power of those massive concert subwoofers, that cost $18,000 each and weigh 300 lbs, down to a manageable size, weight and price for people like us. Seriously, these BASSBOSS rank up there with the concert products that are 5x more expensive, thats why they destroy the mass market “subs” that weigh 90lbs. Those things are like regular woofers compared to the BASSBOSS that is a True SUBwoofer on a totally different level.
I’m 5’8, 150lbs and have no trouble lifting, loading and transporting all 3 of my DJ21S subs. Check out my Instagram for BASSBOSS videos: DJKineticKev. The transport platforms are necessary and built to perfection, they roll so nicely.
Build quality is top notch, the enclosures are military grade. I would recommend these to the touring professionals, mobile 1 man show, and even the home listener that craves Liquid Bass. I especially suggest BASSBOSS for clubs and party spaces. The cost to performance is unmatched.
I am happy to give product demonstrations in the the Tri-State area, Philly, Jersey and Delaware. Inquire through Insta: DJKineticKev
