It is fantastic... sounds great with my bass guitar, sounds great with recorded music, love that I don't have to check it for limiting since it seems just do that all by itself.

This speaker has a lot of power and I am more than happy and satisfied with my DJ18s subwoofer. I strongly recommend this product.

I use 2 DJ18Ss and a ZV28... I break lights and knock stuff off walls!

This was my first piece of pro audio equipment and I was super scared at first of spending so much money with this company, but now I wouldn’t recommend any other brand of subs!

Submit a service request →Notes you never
knew were there.
Goes lower than the rest.
A single 18″ neodymium driver tuned for the lowest notes: the DJ18S is flat to 27 Hz, far lower than the average sub can reach. When the notes go deep, you'll hear what you've been missing on sub-par subs. The rave-meister box that keeps rattling the roof all night, every night.
Twenty-five hundred watts of clean punch.
2,500W of Class D power on a 4.5″ CCAW voice coil. Higher rail voltages slam the peaks while sustained output keeps the low end liquid down to an earth-shaking 27 Hz.
The secret ingredient is powerful DSP limiting.
Five limiters work in concert, including thermal, excursion, and clipping, each protecting the driver differently. Built so deep into the DSP you'll never catch them working: the woofer takes everything you throw at it 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 juice worldwide, and a high-pressure polyurea shell with weather-sealed connectors keeps the electronics safe from the elements. Play anywhere, you're good.
Built like furniture. Armored like a tank.
CNC-machined 18mm Baltic Birch with dado joinery and pervasive internal bracing, wrapped in impact-resistant polyurea. Integrated handles and interlocking nylon sliders for ground-stack precision. Built to still be working the day you retire.
Sixteen presets on the box. Up to 100 in the app.
96 kHz DSP with 16 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.
