Crushing, inescapable,
monstrously beautiful.
Release the Kraken.
Four 21″ neodymium drivers and 10,000 watts: the most powerful subwoofer system we've ever designed. The sub you bring when the field needs to shake and the front row needs to feel it in their chest. There is no comparison for sheer output-to-size ratio.
Massive headroom.
10,000W across four discrete 2,500W channels: each driver gets its own, reducing thermal load. Higher rail voltages slam the peaks while sustained output keeps the low end liquid.
The secret ingredient is powerful DSP limiting.
Five limiters work in concert, including thermal, excursion, and clipping, each protecting the drivers differently. Built so deep into the DSP you'll never catch them working: the drivers take everything you throw at them while the transients stay clean. Push it stupid-loud and it stays bulletproof.
Parties anywhere, in any weather.
An auto-sensing 100–240VAC power supply delivers reliable performance worldwide, and a high-pressure polyurea shell with weather-sealed connectors keeps the electronics safe from the elements. Plug in anywhere, play anywhere.
Eight handles. Sixty years of plywood science.
CNC-machined 18mm Baltic Birch with dado joinery and pervasive internal bracing, wrapped in impact-resistant polyurea. Eight steel bar handles and interlocking nylon sliders for ground-stack precision. Built to still be working the day you retire.
Eight presets on the box. A hundred more in the app.
96 kHz DSP with 8 onboard presets, switchable in real time, plus storage for 100 more over the network with ControlBASS. Dial in your repeat venues once, save them, and every setup after is quicker.
Built for
these gigs.
The deepest, loudest bass a single cabinet can move.
Kraken-MK3 is the answer.
If your gig calls for something different, we'll point you to the sub that's right for you.

For those small, intimate gigs—no more than 200 people—I’ll often choose between rolling out 2 ZV28s or 2 Krakens, running them at just 60%. Since I lay the ZV28s on their sides, the footprint is practically the same either way. And man, they sound so good even at 60%. I didn’t even turn the Diamons all the way up because the space was so small, but I still had plenty of headroom to drop some massive low end when the moment called for it. Those drops… when I gave it a little extra power—the look on people’s faces was priceless. Smiles all around.

BASSBOSS are all good vibrations. Physically and metaphorically speaking. They’ve poured all their time into something that was really lacking, Low End, and it really shows. Not only do their subs look good on paper but they sound and feel even better.

I just wanted to thank you for the great speakers. (The DV12 tops and VS21 subs) sounded so good at our Playa camp this year and brought a lot of cool people over asking “what are those?!” The setup/strike was simple enough that I felt comfortable letting everyone help, and finding the correct gain/pass/presets was a simple matter of trial and error that took about 10 mins once the DJ found his groove. The entire setup pulled only 10% of our generator’s capacity at full honk.
