OWN THE
ROOM

The double-18, done right.

Two 18″ neodymium drivers and 5,000 watts. The original road warrior, battle-tested in clubs, festivals and touring rigs. Plenty of double-18s exist. Truck-packs easy, dominates a room.

5,000 watts. No power-sharing.

5,000W across two discrete 2,500W channels: each driver gets its own. Higher rail voltages punch through the peaks, with reserve to spare when the drop holds.

Limiters watching your back.

Five limiters work in concert, including thermal, excursion, and clipping, buried deep in the DSP. This lets the drivers take everything you throw at them and the transients stay clean.

The storm won't end your night.

The auto-sensing 100–240VAC supply runs on any grid, and IP65-rated connectors under a high-pressure polyurea shell keep the electronics safe when the weather turns. Plug in and play.

SSP218-MK3 cabinet detail showing build quality

Built like a Brick SH.

CNC-machined 18mm Baltic Birch with dado joinery and internal bracing, wrapped in impact-resistant polyurea. Steel bar handles and nylon sliders for ground-stacking.

Dial it in once. Done.

96 kHz DSP with 11 onboard presets that switch in real time. Store up to 100 more over the network in ControlBASS, so your regular rooms load in seconds instead of minutes.

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.

PRESET 01

70 Hz upper crossover

Cabinet display: SSP218 30-70LR

Use it when your tops take over at 70 Hz or higher with a Linkwitz-Riley high-pass filter. Gradually reduces rumble below 30 Hz.

Low-cut:: 30 Hz · Butterworth
Upper crossover:: 70 Hz · Linkwitz-Riley

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.
