Soul-Bending Bass, Mind-Relieving Reliability


You need a rock-solid, rough and ready high-performer that keeps it coming year after year. Done.

The SSP218 offers an extremely cost-effective solution for those who need big bass for the broadest range of applications, providing huge low end for the price, and proven reliability.

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.


Hand-Built Cabinets

SSP218_ Front_1200The SSP218 is a vented, direct radiating dual 18 inch subwoofer that is tuned for optimal driver performance and linear frequency response from 30Hz to 100Hz. The cabinet features ultra-rigid construction with extensive bracing.

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

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.

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 top to facilitate interlocking the boxes when stacked. There is also a second pole socket on one end to facilitate their use standing tall to hold the tops up higher when fewer subs are required.

There are two handles on each side. The amplifier recess is designed to also serve as a handle on the back of the cabinet.

Ideally suited for use as a professional touring subwoofer, its truck-pack dimensions are compatible with 90″ and 96″ truck widths and up to four boxes can be stacked and transported on a single dolly cart. This allows 16 subwoofers and their 64,000 watts of amplification to be transported in as little as 5′ of 96″ wide truck space or 12 boxes and 48,000 Watts in 4′ of 90″ truck space. On their custom-fit wheel carts with locking casters, stacks of 2 or 3 SSP218s can be rolled into place and used without the need to remove them from their carts. For added flexibility, the SSP218s can be stacked on their carts facing forwards or in cardioid configuration.

Prodigious Amplification

A 4000W 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.

Capable of delivering 4000W of continuous output. This ensures the amplifier isn’t the limiting factor in the output of low frequencies. Providing abundant power prevents overheating issues. It virtually eliminates the damage that clipping an amp that’s too small can cause.

Rugged Drivers

All that electrical power is converted into acoustical energy by a pair of 18″ neodymium motor woofers.
These premium-quality, drivers feature split-wound 4″ copper voice coils, and peak-to-peak excursion capability of up to 56mm.

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.

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.

Never Blown a Driver!

Justin Emert, Barcelona

Mad Classy at Barcelona Nightclub has had four SSP218 Profundo Subs for five years of intense dubstep and we’ve never blown a driver! These are the most musical subs out there and they are solid. They’re waterproof so if somebody does something stupid, I can just hose them off, and I have…


I switched to BASSBOSS!

 Albert Caballero, Stage, Lights & Sound

Stage, Lights & Sound Company has been using Meyer Sound for years. I was at a festival and a friend of mine was running the BASSBOSS Subs. I was floored by the sound levels BASSBOSS was able to achieve using half of the number of cabinets. From that point on, I switched to BASSBOSS!


Why mess with anything else but the best for bass?

Vincent Salvaggio, Republic Live

Republic Live been open for 7 years now. It holds 800 people and is the best spot for DJ shows in Austin. Pretty much every EDM and Dubstep artist has played here over the last 7 years, and we have used BASSBOSS products since the beginning. We can’t wait to do a full BASSBOSS system at Republic Live…!


Can you hear me now?

Frank H., Texas School for the Deaf

OMG… I never thought there would be such efficient speaker systems available.  BassBoss staff were so very helpful in making the determinations of the perfect fit for out 900 seat auditorium.  What a system!


10 out of 10.

Aaron Miller, The North Door

The North Door in Austin has four SSP218s. Your product is amazing and our room sounds beautiful! Nothing but rave reviews. Thanks!



Pea Trombley

Besides being thunderingly awesome, these subs are incredibly efficient and in my personal opinion the best value for massive SPL with incredible clarity at the lowest lows.


The Beast

Ian Lewis

This sub makes accurate notes that other subs like the LA2100p and LS801 could not make cleanly. Every time I play my SSP218 Sub I say “what an investment.” This sub is smooth and hits hard. I call it ‘the beast’.


Very impressed, can’t wait to get the next batch!

Dan Bouchard, Audio East

Audio East, Inc’s experience with BASSBOSS has been fantastic. The white glove service and expertise really made the transition into the product seamless. The performance of our twelve SPP218′s has been outstanding and we have had no issues filling any venues with organ shaking low end on the DayGlow Life in Color Tour.


We chose BASSBOSS after blowing up every other viable option on the market.

Gregory Selph, Treehouse Miami

Treehouse is Miami’s premier techno – underground dj venue, who specialize in European techno bookings weekly. Treehouse installed six SSP218 “Dub-ill 18” Profundo Subwoofers and four X2C Deuce Motiv Bass Horns on their dance floor in Spring 2012, and added two DiaMon DJ112 Monitors in December 2012. In August 2012 we were voted Best Small Music Venue by the Miami New Times.

We broke Dynacord Alpha System subs – which btw was my favorite system before finding BASSBOSS. We tore the ass out of EAW Subs, replacing 8 drivers like 4 times in 6 month period – that’s 32 drivers!! We didn’t even bother with Funktion One – they have no low end. We blew up one JBL sub system and couldn’t even hear another. We blew up Meyers, believe it or not, after the rep told us no way he has anything to worry about – “You can’t hurt my equipment.” Boom. We fried 3-4 Crown and MC2 amps in the process – our sound tech labor invoices, let alone the parts, were sucking us dry. Customers were emailing and blogging about our amazing DJ lineups and constantly failing sound systems.

These days, DJ’s demands on equipment are consistently surpassing the status quo of just a few years ago. Low end demands are the greatest, and often the weakest point in a sound system – BASSBOSS is directly the opposite. BASSBOSS makes low end effortless – waterproof – drink proof – dj proof – self powered – self cooling – self monitoring – self limiting – and just bass crushing all wrapped in a tight little package. Wheel it in – plug it in – ready to begin.


Thanks for a killer product!

Travis M., Independence Community School District

I’ve been grinning from ear to ear with these cabs! Because of these cabs and how well they sound, I’d be willing to go as far as calling it job security! We’ve found many ways to utilize them from great cinematic effects in the theater like the roars of Shrek this year with our spring musical to to thunder and lighting for the Jr. High Wizard of Oz last spring! We’ve managed to use them for holiday concerts with pipe organs; a civil war theme concert with mic’d marching bass drums! Often times we’ve realized that even if we don’t necessarily need to use them for an event, we usually find ways to implement them and things are instantly great. In fact most times I’m told by my coworkers, our productions are usually a “spectacle” haha!”


Most MUSICAL sounding subs

David Bedrack

The BASSBOSS were the most MUSICAL sounding subs of the set under test. No specs can measure that. Many sound either smeared or like cardboard boxes and the best ones still lack the definition of the BASSBOSS subs.
