2,500 watts of clean punch.

2,500W of Class D power on a 4.5″ CCAW voice coil. High rail voltages snap the kicks, and sustained output carries the low end down to an earth-shaking 27 Hz.

Floor it. The DSP has you.

Five limiters guard the driver, including thermal, excursion, and clipping, and they stay out of earshot. Push the fader all night: the woofer takes everything you throw at it.

Rain rolls in. Bass rolls on.

An auto-sensing 100–240VAC power supply delivers reliable juice worldwide, and a high-pressure polyurea shell with IP65-rated connectors keeps the electronics safe from the elements. Play anywhere, you're good.

DJ18S-MK3 cabinet detail showing build quality

Birchwood with hard armor.

CNC-machined 18mm Baltic Birch with dado joinery and internal bracing, wrapped in impact-resistant polyurea. Integrated handles and nylon sliders for ground-stacking. Still thumping after your kids graduate.

Repeat gig, instant setup.

Pick from 16 onboard presets on a 96 kHz DSP, switching in real time. ControlBASS saves up to 100 over the network, so the venue you nailed last month sounds that good again tonight.

Get Deep.

From the Family

The DJ18S-MK3 in its natural environment,
mobile rigs, club floors, and anywhere the brief is "make it bump."

That's what they said.

Aaron Linder

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.

Isidro Lopez

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

Jason Perry

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!

PRESET 01

65 Hz upper crossover

Cabinet display: DJ18S 27-65LR

Use it when your tops take over at 65 Hz or higher with a Linkwitz-Riley high-pass filter. Gradually reduces rumble below 27 Hz.

Low-cut:: 27 Hz · Butterworth
Upper crossover:: 65 Hz · Linkwitz-Riley

PRESET 08

Cardioid · rear-facing cabinet

Cabinet display: Cardioid 85LR

Use it on the sub facing away from the audience in a cardioid setup. Tops take over at 80 Hz or higher with a Linkwitz-Riley high-pass filter.

Low-cut:: 27 Hz · Butterworth
Upper crossover:: 80 Hz · Linkwitz-Riley

The cabinet display name and stored filter values differ for this preset. The graph uses the stored filter data; the cabinet display name is retained for identification.

PRESET 16

Cardioid · rear-facing cabinet

Cabinet display: Cardioid 85BW

Use it on the sub facing away from the audience in a cardioid setup. Butterworth low-pass at 80 Hz; start with LR presets for a sub/top crossover.

Low-cut:: 27 Hz · Butterworth
Upper crossover:: 80 Hz · Butterworth

The cabinet display name and stored filter values differ for this preset. The graph uses the stored filter data; the cabinet display name is retained for identification.

Illustrative high-pass and low-pass filter response. This does not show the complete loudspeaker response, room coverage or all DSP processing.

Up to 100 stored presets via ControlBASS

Manage, name, and recall: all over Ethernet.

Select a preset

Start here, then listen and adjust on site. Relative levels, placement, the room and your speaker combination affect the result.

Linkwitz-Riley low-pass: try tops with an LR high-pass at the same frequency or higher. Relative levels can shift the acoustic crossover; listen and adjust on site.

Filter details and terminology

Low-cut (high-pass): Gradually reduces output toward lower frequencies. The response is already reduced at its cutoff; it does not stop abruptly there.
Upper crossover (low-pass): Gradually reduces output toward higher frequencies. Subwoofer and top responses overlap around the crossover.
Linkwitz-Riley (LR): A recommended starting point for the sub/top crossover. For a top's LR high-pass, try a sub's LR low-pass at the same frequency or lower. For a sub's LR low-pass, try a top's LR high-pass at the same frequency or higher. Verify the combination on site.
Butterworth (BW): A maximally flat passband with less attenuation around the cutoff than a Linkwitz-Riley filter of the same order. Lower-frequency BW high-pass presets are useful for full-range bass extension. Start with LR presets for a sub/top crossover.

PRESET 01: Cardioid · rear-facing cabinet

Reduce bass behind the system.

A cardioid setup uses forward- and rear-facing cabinets to reduce rearward bass. Apply the cardioid preset to the cabinet facing away from the audience. BASSBOSS recommends two forward-facing cabinets for each rear-facing cabinet. Placement, spacing, frequency and relative levels affect the result.

Arrange the cabinets.

Start with BASSBOSS’s recommended two-forward, one-rear configuration and the model’s setup guidance.

Set the rear-facing cabinet.

Select the appropriate cardioid preset on that cabinet. Use the appropriate forward-facing presets on the other cabinets.

Check the result.

Listen and measure in front of and behind the system, then adjust the setup as needed.

Illustrative cardioid coverage: more bass toward the audience and reduced output behind the array. Actual coverage depends on the setup.
