Punchy galore.

2,500W of Class D power on a single 4.5″ CCAW voice coil. Plenty of voltage for big, clean peaks and the stamina to keep the lows rolling down to 30 Hz.

Push it. It can take it.

Five limiters, including thermal, excursion, and clipping, work so deep in the DSP you'll never hear them. Run it hot: the woofer takes the hits and the transients stay clean.

Spills and squalls? No problem.

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

CNC-machined 18mm Baltic Birch with dado joinery and internal bracing, wrapped in impact-resistant polyurea. Integrated handles and foot pockets for ground-stacking. It'll outlast your van.

Save the sweet spot.

96 kHz DSP with 16 onboard presets and real-time switching. Save up to 100 over the network with ControlBASS, and your favorite setups are a tap away at every repeat gig.

Good Lord!!! Just tested my new SSP118s - this was a single sub in the middle of a huge lawn, on top of a platform, on the casters and paired with two RCF NX932a tops…. So one of the least ideal locations and setups for a sub and it STILL HIT! I picked a song to show case all the low note precision, speed and clarity for you guys.

Barrett Clark

Mix Engineer | Katabatik Sound System

Props to BASSBOSS! The depth and clarity is on par with Meyer, D+B, and L-Acoustic, all of which I run frequently as a touring FOH engineer. The SSP118 subs have depth unheard of for a single front firing 18”. I was afraid to turn it up all the way, my 140+ year old house might not be able to take it!?(Barrett, we miss you.😥)

I am from El Salvador and we don’t have BassBoss here, but after researching I found outabout it and with your help I decided to import 2 SSP118 and 2 DV12s, and let me tell you, everything that you read about BassBoss is true. The sound is amazing! Clear and powerful! We played house and techno and everyone was happy about how tight the bass is. There is nothing like it at this price point, and I am happy to introduce this brand and quality in my country. I am being asked now to rent it for events. You definitely need 2 people to set up. I was able to fit everything in a 4runner.

Brett McCutcheon

I have BASSBOSS SSP118s and they do awesome, really with all music and when I do really deep stuff I add the ZV28 to supplement, I used just the SSP118s for quite a while and got tons of compliments! I will say the SSPs have been one of my best investments honestly and one thing I love about them is you dont have to worry about watching limit lights. You can push them and push them it is crazy!

PRESET 01

Use it when your tops take over at 75 Hz or higher with a Linkwitz-Riley high-pass filter. Gradually reduces rumble below 30 Hz.

Low-cut:: 30 Hz · Butterworth
Upper crossover:: 75 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.
