One box. Plays everything.

A single 18″ neodymium driver and 2,500 watts in a box one person can load solo. From dusk to dawn it's the multi-genre crowd-pleaser, the party hound that just won't stop. One box, loads solo, plays everything.

Punchy galore.

2,500W of Class D power on a single 4.5″ CCAW voice coil. Higher rail voltages slam the peaks while sustained output keeps the low end liquid down to 30 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 performance worldwide, and a high-pressure polyurea shell with IP65-rated connectors keeps the electronics safe from the elements. Play anywhere.

Bullet Proof.

CNC-machined 18mm Baltic Birch with dado joinery and pervasive internal bracing, wrapped in impact-resistant polyurea. Integrated handles and interlocking foot pockets 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.

Have you grown out of alphabet soup subs?

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.

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.

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.
