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.

This is a wonderful equipment for DJ! It is playing the low range that can not be compared with other subwoofers. It surpasses Martin’s triple 15-inch woofer and two 18inch L-Acoustics subs. I can listen to the sounds that I could only listen to at the concert venue in my room. My friends call me crazy, but the music is asking for it. (Translated from Japanese by Google)

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.
Twenty-one presets on the box. Up to 100 in the app.
96 kHz DSP with 21 onboard presets, switchable in real time, plus storage for up to 100 over the network with ControlBASS. Dial in your repeat venues once, save them, and every setup after is quicker.
Take a dip.
