OWN THE
ROOM
The double-18, done right.
Two 18″ neodymium drivers and 5,000 watts: the original road warrior, battle-tested across clubs, festivals, and touring rigs for years. There are plenty of double-18 subs in the world. This is the one that's done right. Truck-packs easy, carries a room.
Five thousand watts. No power-sharing.
5,000W across two discrete 2,500W channels: each driver gets its own. No power-sharing, no thermal compromise between drivers. 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.
Built like furniture. Armored like a tank.
CNC-machined 18mm Baltic Birch with dado joinery and pervasive internal bracing, wrapped in impact-resistant polyurea. 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.

10 out of 10. Our four SSP218 Subwoofers are amazing and our room sounds beautiful! Nothing but rave reviews.

After Ultra Music Festival (2012) David demoed a system for us. His demo was impressive to say the least – everything attached to the walls shaking and falling down. The equipment wasn’t even working hard and it had just taken beating after beating in the Miami heat and salty humidity at Ultra.

We have been getting nothing but compliments in the studio about those speakers and they sound amazing on our mobile events. These can become the defacto standard for the Mobile world. They sound unbelievable and I just wanted to let you know!! You nailed it with the DV12's.
