    SSP118 Powered Subwoofer

    New features on the updated SSP118-MKII Sub, available now. 

    We've updated the SSP118 with upgrades for both form and function.

    New port design. By removing the grill from over the ports, we've improved the sound by reducing possible turbulence. This update also increases cooling capabilities by greater air flow through the ports.  

    Two integrated through-cut pocket handles on each side. Offering more grab points and opportunities to grip from different angles, so it's even easier to move the SSP118 Sub. The handles are also integrated with the new ports for improved bracing of the cabinet structure.

    Providing massive output at and above 30Hz. Modern electronic, jazz, reggae, R&B, rap and hip-hop music emphasize bass and put tremendous demands on low frequency loudspeakers. The SSP118 delivers the energy and power of modern music and it is built to take the stress of doing so continuously, to the extremes, without fail.

    Optimized for remarkably deep bass response. In a cabinet of manageable size, SSP118 Subwoofers are each loaded with a single 18" long-excursion, neodymium motor, low frequency driver. Each driver has a 4” voice coil and is rated for 1500W nominal power handling, 3000W program power handling.

    Practically impossible to blow drivers. Thanks to 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. The protection systems prevent thermal overload of the voice coils and minimize long-term thermal compression while having virtually no effect on the transient response and peak output of the loudspeakers.

    Extremely flat, delivering response that is +- 3.0dB from 30Hz to 100Hz. No equalization is required to achieve this response. Unlike designs that require equalization, the SSP118’s tone, response and sensitivity are native to the design. Systems that require processing to achieve their stated response are still subject to the physical excursion and thermal limits of their drivers. Boosting low frequency EQ to achieve extended low-frequency response results in excessive distortion or woofer damage at full power unless limiting is applied. The limiting necessary to prevent failure also prevents the realization of their claimed frequency response at full power. The SSP118 does not suffer from these limitations. It faithfully delivers the low bass where most others either roll off or die trying.

    Finished in extremely durable black textured weatherproof polyurethane coating. A top-mounted pole socket in each SSP118 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 when stacked. The woofers' cones are made from a waterproof fiber matrix which can withstand exposure to spills and rain and can be wiped clean with a damp cloth.

    Engineered to work hard and continue to work where others fail. The BASSBOSS warranty provides 6 years of coverage against defects in materials and workmanship. The warranty covers failed drivers, including burned voice coils, for 2 years from the date of purchase. If a voice coil, or anything else, fails within the warranty period, replacement parts will be provided without charge. (See warranty documentation for complete details). With the peace of mind afforded by plentiful, clean, undistorted output and comprehensive protection systems, you can confidently push the SSP118 to levels and depths that would otherwise require more or bigger cabinets.

    Available with a number of optional accessories. The SSP118 Custom Fit Wheel Cart allows for easy movement of one or two subs. Custom Made Protective Covers protect your subs and keep them looking new for years to come. The option to have the amplifier mounted in a rack chassis is also available, please contact us for details.
