For Mobile Professionals who provide superior sound quality. The SSP118 delivers premium sonic experiences unavailable with other manufacturer’s single 18″. This single cabinet will replace 3-4 competing cabinets, for more sound out of less space and cost. Why carry more?

WHY CHOOSE A SSP118 Subwoofer?

It's The Nightclub Experience, Mobilized: Turn heads when you turn it on.

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 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.


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.


The SSP118 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-built 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.


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.

Capable of delivering 2400W 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.

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.


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.


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.


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.
