Ninja Sub

The BASSBOSS SSP215-MKII Low-Profile Subwoofer delivers output to frequencies lower than many double 18” cabinets, and it does so using 25% less space than the SSP218. It’s tuned low, for use as a proper subwoofer, with long-excursion, low distortion woofers, to deliver deep and rolling lows. It also has a tight, punchy and articulate character because of the lower mass of the 15” cones.


Ideal for the professional who needs significant bass output but has limited space. The SSP215-MKII will comfortably take the place of common double 18” boxes without giving up output or low frequency extension to bigger boxes. The SSP215-MKII can fit under low stages, be flown in low ceilings and can be tucked in corners or between furniture where larger boxes would not fit. It’s 29.5” deep, making it a perfect truck-pack size, especially considering up to 6 cabinets can be transported on a single rolling cart. Its largest dimension is 48”, so when stood up it can serve as a stack platform for getting the top boxes up above the audiences’ heads, just like a double-18”.


The smallest frontal dimension is only 17.5”, allowing lots of placement options. For venues, the low-profile box can fit under stages that are too low to accommodate a double-18” subwoofer, and yet it can easily power packed dance floors with deep and punchy bass. For portable systems, the SSP215-MKII can be placed in front of stages, serve as a monitor platform, as an extension of a stage or even placed under a table. It’s size and shape make it remarkably easy to disguise in places where subwoofers need to be heard and not seen.


Providing massive output at and above 35Hz, reliably, consistently, and with great fidelity. 15” woofers are often preferred for their articulation and impact. The SSP215-MKII puts tremendous power and deep tuning behind 15” cones to provide the best combination of tight punch and extended depth from a compact cabinet. The result is a 15” based subwoofer with the versatility required to translate the power of dance tracks, modern country, blues, rock, R&B and hip-hop with amazing presence and heavyweight power.


The SSP215-MKII is powered by a 4000W RMS amplifier. This is a continuous rating, not a peak or burst rating. The amplifier is equipped with a comprehensive digital signal processor that eliminates the need for outboard processing. It provides high-pass, low-pass and limiting functions as well as integrating the alignment with all other BASSBOSS subs and tops.

The DSP also features a Cardioid setting for when multiple cabinets are deployed. The amplifier is recessed into the back of the cabinet at sufficient depth to ensure adequate cooling and to protect the connectors when the cabinet is placed against a wall. The recess also protects the amp from most spills and even light rain

We are very satisfied with the new Bassboss system! It’s well worth the money. We put it to use at a wedding last weekend and at Bar also. The sound is so clear. I highly recommend Bassboss to anyone! You will be 100% satisfied!!!

Sami Scoda is excellent to work within sales. They helped us get everything we needed to add to our DJ Business. Finance department did an amazing job as well.

They sound and feel so good.

Carlos Alfaro, Aguilas Centro Familiar Cristiano

We love these subs! they sound and feel so good. 0 complaints. We got a lot of compliments from members of the church. We’re happy with our purchase. Thank you for all the support!

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!


The combination of extremely rugged, very high power handling, long excursion drivers, carefully optimized cabinet and port design and several effective but transparent protection systems allow this double 15” subwoofer to provide output levels and depths that compete with bigger, bulkier and far less articulate double 18” subwoofers. The protection systems effectively prevent thermal overload of the voice coils and minimize long-term thermal compression whilst having virtually no effect on the transient response and peak output of the loudspeakers

and Durable

Finished in extremely tough black textured weatherproof polyurea coating, with a top-mounted pole socket, the SSP215-MKII provides for mid-high loudspeakers to be mounted on a straight speaker pole above the subwoofer. The enclosures also feature four large rubber feet and corresponding recesses in their tops to facilitate interlocking the boxes with each other and with the SSP218s when stacked. The feet also interlock with the transport carts, which help to ensure that the cabinets get into and out of venues safely and unscathed. The woofers’ cones are made from a waterproof fiber matrix and are protected by a powder-coated, perforated steel grille.

True Specifications

BASSBOSS technical specs are based on measurements of continuous performance 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.

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.

Deep Dive

Hand-Built Cabinets

The SSP215-MKII is a vented, direct radiating dual 15 inch subwoofer that is tuned for optimal driver performance and linear frequency response from 35Hz to 100Hz. The cabinet features ultra-rigid construction with extensive bracing.

BASSBOSS cabinets are hand-assembled 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 powder-coated, 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 SSP215s can be rolled into place and used without the need to remove them from their carts. For added flexibility, the SSP215s can be stacked on their carts facing forwards or in cardioid configuration.

Optional Suspension System. 16 X 3/8-16 Threaded Flypoints

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 15″ neodymium motor woofers. These premium-quality, drivers feature split-wound 4″ copper voice coils, and peak-to-peak excursion capability of up to 46mm.

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.
