Bad-boy for mobile DJs and small venues, a single 18″ cabinet that delivers like a double 18″. With low frequency output down to 30 Hz and sustained output up to 130 dB, you can easily bring serious bass for mid-size rooms with a single cabinet.

Each SSP118-MKII Subwoofer offers the SPL of two, three and in some cases four mass-market subs, with deep-bass output competitors don’t touch, in a much smaller overall package.

Fits in a hatchback, rolls in and out on a custom wheel cart. Slick.

QuoteIf you want premium bass in a small package, this is the way to go.

I used two on a medium sized event and it is astonishing! Where I would normally bring four JBL SRX718s, two SSP118s blew them away. Even one sub is already overkill on my DJ events. It’s better to have more than being short on bass. ”

Jerome P. – DJ Onyx on

Don’t hold back!

BASSBOSS subs are optimized for full-power usage.

Multiple proprietary protection technologies ensure that the woofers remain within their excursion and thermal limits, so they don’t break or burn like other subs. BASSBOSS provides much higher levels of deep bass than mass-market subs, reliably.

With plenty of headroom to keep up with the most enthusiastic crowd and not run out of bass.

So turn it up, and keep it up. BASS is good for you.

BASSBOSS not responsible for noise complaints.


True Specifications

BASSBOSS technical specs are based upon measurements of continuous performance capabilities in normal usage. Other manufacturers may specify output based on calculations rather than measurements; measurements outside the operating bandwidth; or on ‘Burst’ or ‘Peak’ readings.

BASSBOSS specifications are conservative compared to most manufacturers. They reflect what the products will achieve, consistently, in the real world. Since the real world is where you’ll be using your gear. 

Read more about BASSBOSS Designer David Lee’s specifications philosophy on ProSoundNetwork.

Our proactive philosophy causes specifications to be subject to change whenever improvements are made.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specifications that are inflated over what can actually be achieved. BASSBOSS real world output specifications are provided as “Maximum Sustained Output” ratings, which reflect actual measured, continuous output levels.

Hand-Built Cabinets

BASSBOSS SSP118 MK-II Powered SubwooferThe SSP118-MKII  is a vented, direct radiating single 18″ subwoofer with extensive bracing, easy portability and frequency response that rivals many double-18″ subs. Very large ports maximize low frequency performance at high output. The ports exit outside the perimeter of the woofer grill to minimize air flow noise. The port walls, handles and amplifier recess are all designed to serve as braces in addition to their primary purposes, making the cabinet extremely rigid. The port openings and amplifier recess also offer grab points on the front and rear of the cabinet.

BASSBOSS cabinets are hand-assembled in the USA. Constructed from 18mm Baltic Birch plywood, using dado joints, screws and advanced composite adhesives.

A top-mounted pole socket provides for mid-high loudspeakers to be mounted on a straight speaker pole above the subwoofer. The enclosures feature four large rubber feet on the bottom, with corresponding recesses in the opposite side to facilitate interlocking the boxes when stacked.

There are two handles on each side. The amplifier recess is designed to also serve as a handle on the back of the cabinet and the port openings allow lifting from the front.

Created to stand up to intense usage. The cabinet is finished in an extremely rugged, black polyurethane coating. Drivers are protected by a black powdercoated, perforated steel grill, and the amp is recessed into the back of the cabinet for protection from damage, direct sun and moisture.

Optional Flying Hardware. Includes side-pull anchors and/or shoulder eyebolts and a suspension system with 16 x M10-1.5 threaded flypoints.

Prodigious Amplification

A 2400W RMS amplifier with integrated, comprehensive DSP is included. The amplifier is rated for RMS output using continuous sine wave signal.

This is not a Peak or Burst power rating. BASSBOSS uses only continuous RMS power ratings because you’re not going to be using your sub in millisecond bursts. For subwoofer applications, Peak and Burst power ratings are largely irrelevant.

The amplifier is capable of delivering 2400W of continuous output. This ensures the amp isn’t the limiting factor in the output of low frequencies. Providing abundant power prevents overheating issues and virtually eliminates the damage that clipping a too-small amp can cause.

For larger events, several arraying options are available. Block arrays, side-by-side arrays and front/back Cardioid arrays can be deployed securely thanks to the interlocking feet. Presets are included in the DSP.

Rugged Drivers

All that electrical power is converted into acoustical power by an 18″ neodymium motor woofer. This premium-quality driver features split-wound 4″ copper voice coil, and peak-to-peak excursion capability of up to 56 mm.

High-intensity Neodymium magnets are lighter and provide higher efficiency so the result is a lighter and louder cabinet. Split-wound coils produce a more linear force through the range of movement of the cone, which results in lower distortion and improved linearity at high output.

The cones are waterproofed to protect them from possible, accidental exposure to moisture such as rain or spilled beverages. Waterproofed woofer cones also permit the cleaning of drivers that have been soiled in a dirty or dusty environment with the use of a damp cloth. Keep the amplifiers dry and party on!

Waterproofed cones in all products. Optional weatherized and weather resistant loudspeakers have the same acoustical performance as our standard options. If your system is likely to be exposed to rain, ask about IP rated amplification options. If you have need of a system for outdoor installation, ask about Weatherized products.

Focused Tuning

BASSBOSS subs can be connected directly to your mixer with nothing but signal cable in between. The built-in processing is comprehensive and yet minimal manipulation is applied to the signal. The processing includes only a high pass filter and a low-pass filter. There is no need for any EQ in the signal for the speaker to provide a broad, flat frequency response. A sophisticated limiter system protects the woofer from thermal and over-excursion damage.

Plug-and play with peace of mind. Multiple, sophisticated protection systems make the loudspeaker virtually indestructible. You can turn on and turn up, all night, without fear of over-driving to the point of damage.


It was worth every penny!

Trevor Bidhadar, ESK DJ

I bought two SSP118’s and I absolutely love them. I want my speakers to be compact, lightweight, portable, and most importantly – rock the dance floor. I knew the SSP118 was a serious subwoofer. The first time I heard it I couldn’t stop thinking about it. A year later, I finally decided to buy mine and it sure was a wise investment. I was scared it would be too heavy to transport as a mobile private event DJ. I’m happy to say it is surprisingly light for a subwoofer of its kind, and with a dolly transportation is super easy. Two of them fit perfectly in the bed of my truck. The sound is amazing. I don’t want to use any of my other subwoofers anymore.

The best thing about my purchase was the BassBoss customer service experience. Sami and the team have gone beyond expectations. They were quick to provide order updates, tracking information, and answer questions. The team know what they are talking about; you can trust their advice. I mentioned I scratched my subwoofer just expecting a “sorry to hear that”, nope! The team sent me the exact paint to use to touch it up. This is by far the best customer service experience I have ever received from a company related to my DJ business.

Exactly as described!

Charles Veale, The DJ Dad

I have owned a few higher end consumer subs over the past few years and most of them are are pretty similar in how they sound with only slight differences. The Bassboss SSP118 was a totally different beast. I realized what I was missing was that “Power” wasn’t how loud a particular frequency of a sub sounded, but how it “feels” and sounds. I was missing the shockwave that was created by the SSP118 with my other subs. It wasn’t necessarily louder than the other subs, but the perception of power was night and day. The really low stuff was moving more air than my other subs ever did and the overall sound was really smooth across the entire range of the sub. You will enjoy listening to music more with these. While you are not going to get concert levels with the SSP118, you get the same character of sound that you would expect from a high-end concert setup just at lower levels (obviously). No frequency left behind!

I am a mobile DJ and being portable is something I was interested in and thankfully these didn’t feel as heavy as the specs indicated. I think that is due to the weight being evenly distributed in the sub and plenty of places to get a hand to lift them. I lift it regularly by myself. Nice.

Overall, these were slightly more expensive than my other subs, but they delivered much more and I would buy several of these in the future.

Customer support is amazing. I am a small blip on their sales radar, but they treated me like I was important and took the time to answer all my questions. Shout out to Chris Scoda. David Lee even called me and gave me some good info. You guys rock.

You get what you pay for.

James Chemaly

Wow. What a great product and service. You get what you pay for. It will literally take five or six lesser subs to equal one. And, the follow up service is unreal in a world where once most companies have your money, they are done with you. BASSBOSS has called and emailed me unsolicited to follow up multiple times.

Never heard anything like it.

Kirby Oliveras, Guitar Center Pro

The BASSBOSS SSP118 sub is a little more expensive but, in my 20 plus years in audio, I’ve never heard anything like what they make. They are easily twice as loud as any single sub on the market with a lower USABLE response as well.  I compared this with every other competitor on the market- no one moves as much air. No one.

The sound quality and customer service are great

Tyrus C.

When buying from BassBoss you get great sound and great service from everyone at BassBoss. David helped me plan out everything I would need from now till essentially the end of time. For audiophiles it’s a great subwoofer because it has an extremely clear, well-defined tone. The setup is extremely easy and even with just one SSP118 the sound is phenomenal. I would encourage everyone to buy from BassBoss for any professional sound needs.

BassBoss gear……best investment we have made.

On Your Feet Production

These subs simply sell themselves. They amazed me from day 1 and I have been doing this for about 40 years.

Didn’t event break a sweat

DJ Moses 

The gig over the weekend was great and the sub was even better. I used JBL tops with it and at max volume the sub didn’t event break a sweat… and the JBLs were blinking like it was X-Mas. In most cases, subs can’t keep up with the tops, but in this case I would need to have 2 JBL tops to keep up with one SSP118, and just maybe they may have a fighting chance.

You will FEEL this subwoofer

Michael Khoury

Small Pieces of the ceiling were falling down on my mixer on the very first gig with one MK2! Guests were coming up to me and commenting how they could feel the bass kicking their chest. Best Sub For Mobile DJs that exists. I researched for months and months, asked around, and tried and bought what I thought were the best of the best “Prosumer” subwoofers. I have bought the VRX900 Subs from JBL, QSC’s KS118s, and KW 181s. This BASSBOSS single subwoofer chews them up and spits them out like nothing! Sami Scoda is the coolest and most helpful product expert I have dealt with in my 14 years as a pro musician. Sami was super quick to follow up, and always backed up every single claim with pure facts that were indisputably tested by third party companies. This sub fits in the back of my 2018 Subaru Forester easily with my 2 other tops, wire bag, gig bar lights etc, and I still have room to squeeze in one more. I can’t imagine how two of these would sound, and am saving to buy the next one. You will FEEL this subwoofer. It is not necessary louder than other competitors, but when in front of it you feel as if you are getting hit with the force similar to a huge show, or a GORILLA KICKING YOU IN THE CHEST. Side by side with my QSC KS 118, the KS 118 just gets loud volume wise, but drops off when I play the new hit songs at weddings that go down very low. The MK2 shakes and rattles the chandeliers, and everything in sight, it is an absolute Monster for its size and weight, and anyone who buys this will consider it a wise investment. BEAST and not too heavy. I bought the case and with that can leverage the subwoofer easily into a cart and tip it right into the back of my truck. If I have to lift it completely I also am able to for someone who is 5 foot 7 160 lbs.

Sami Scoda is the best product expert I have ever talked to and knows their stuff. This team is not afraid to compare their products to any competition and will give you realistic expectations!

Perfect for the mobile DJ who believes in “less is more.”

Gold Coast Events Co. 

Perfect for the mobile DJ who believes in “less is more.” At 2400 watts rms, one sub is perfect for coverage between 100-200 people in a small to medium sized hall. After receiving numerous compliments on the quality of the sound, I can say that I am satisfied. It is worth the investment for a quality cab.

I will be buying another soon

Michael Majerowicz | Milk Majer

I have had one opportunity to gig with it and so far it sounded great, clear, and deep! I pushed it to unity on my mixer and opened it up to plus 10 dbs on the sub and still haven’t even clipped it yet. I even had venue staff coming up to me saying they loved it and they heard it in the room next door. I will be buying another soon 🙂

They’re a beast!

Kitt Tremblay, DJ Kitt

I’m a Canadian Deaf DJ in my community and I was searching for sound system speakers that was well built and strong enough to handle anything. The Deaf community loves to feel the music which means to experience clear and deep bass vibration from the music. Bass Boss was, no doubt, the product I needed as nothing else compared when contrasting the specs. I bought four SSP118’s and two DV12’s and I have to say how impressed I am at the product caliber. They’re a beast! I love the fact that the cabinets can pump clear and powerful bass without losing strength and it last all night long. Wow! As soon as the people walk into the room, you see their heads snap and body starting to move like they can’t stop dancing to the beat. People were amazed how much bass they can feel from even just one cabinet. The Bassboss team was super helpful, informative about their products, and love their job. I’m so happy that I am part of the Bass Boss family and proudly use my Bassboss equipment to bring exceptional sound and badass bass to my community.

Awesome low-end punch!

Bob Fleischmann, Reflex DJ Service

I love this speaker and have not heard anything like it in all my years of DJing. My old subs just couldn’t match the clarity and range. I haven’t even pushed them yet – can’t wait for a club gig! I already have compliments on the sound. I am hearing (and feeling) notes come out of this thing that I have never heard out my music before. I have to turn my tops up just to match this sub! The entire room resonated last night at a class reunion. I’ve never heard 80’s music so alive!

I plan on buying two more subs soon from BassBoss! The salesperson, Chris is great. He answered all my questions and made it super-easy to order. Thanks BassBoss.

boss of the basses!


size: cute,

power : awesome,

looks : oh my! this speaker is the boss of all things bass!

No words to describe!

Braulio Cabrera

No words to describe… this outstanding SSP118 unit. I have received my speaker today and I love how it fits just right on the back of my Toyota Camry. Much Love and Respect … for the BASSBOSS team and their hard work … !!

Extremely tight and articulate response!

Christopher Ashbrook, Katabatik Sound

Hands down nothing touches these for their size. Without a doubt these are twice the punch and loudness of any front firing 18″s I’ve used. Extremely tight and articulate response!

BASSBOSS SSP118 is a truly amazing sub for its size!!!

Jerome P.

BASSBOSS SSP118 delivers a clean and powerful bass that can only be heard on some of the popular dual 18 box. It’s a great value, because it comes with a fully transferable, no fault warranty for 2 years (on the woofer), 6 years for the cabinet and customer service is second to none. All quality materials has been used from the ground up to build such a beast!

One cabinet is more than enough when doing a small gig for DJ or live sound reinforcement. I have ordered two of these cabinet and have used both on a medium sized event, without even coupling the SSP118 and it is astonishing! Where I would normally bring four JBL SRX718s.

Thanks to David, Lian and the whole BASSBOSS team for the support during the entire purchase process, shipping and making a satisfied customer. Even after I have received and used the sub, they still have my back.

Nothing comes close hands down

Ricky Dorantes

My subwoofer is the best addition to my dj setup. It is really physical bass you can feel without compromising sound quality. There are really no words that can describe the feeling it gives you. You have to experience the bass. It goes through your body in a surreal way. There is no ear fatigue, no clipping and no distortion whatsoever. Just clean clear bass reproduction.

Nothing comes close hands down. I experienced many subwoofers but BASSBOSS, it’s in a class by itself. I’m super proud to own one and be part of the BASSBOSS family. Plus it’s made here in Austin, Texas USA. Thank You again BASSBOSS!

BASSBOSS team has been excellent to work with. Their passion for music and sounds reflects in their product and customer service. From the moment you contact BASSBOSS they answer all your questions, they listen to your needs and what you’re trying to accomplish. That was very important to me. It made my decision of the sub I wanted an easy choice. The process was enjoyable in every step. I was also impressed by the follow up email BASSBOSS sent to me. I was very satisfied with my purchase. Will be doing business again with them soon.

They sound great in Indoors and outdoors!

John DeVergilio, JD Entertainment

I purchased two SSP118-MKII subwoofers. They are a great addition to my sound system. I do about 60-70 events a year! I’ve used these subs indoors and outdoors and they sound great in both capacities. I’ve also used them with my DJ and Live Bands. I love the deep full bass and the punchiness. I will buy from Bass Boss again! #bassbosscustomerforlife

Sami is a great sales rep. The rest of the team is very responsive and helpful when Sami is not available. I am very happy all around with their support.

The SSP118-MKII Sub is from another galaxy

Mike Swass

You gotta pay the cost to be the BOSS!
Before I get to the review, I’d like to say a word about the service.

They basically run a high end concierge for speaker buying. Anything you need, Sami will provide. This is the way to buy speakers, you won’t regret it.

The SSP118-MKII Sub is from another galaxy. I’ve not heard a stronger mobile sub-woofer in my life.

The DV12-MKII have the lushest, most creamiest sound. Warm and pleasant at very loud volumes.

Be that DJ with the best speakers…. because you can be THAT DJ with the best sounding system.
