    SSP218 Powered Subwoofer

    Incorporating innovative new technologies into rigidly braced, large vented boxes that are optimized for maximum output and reliability. The SSP218 is a loudspeaker system that sustains its output long-term and is practically impossible to blow 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 effectively 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 loudspeaker.

    Very high output, low frequency sound with extremely low distortion. The SSP218 system is optimized for full-power operation and is designed to operate at full rated RMS power throughout its operating range while the woofers remain within their X-max specification. 

    Extremely flat, delivering response that is +- 1.5dB from 32Hz to 100Hz. No equalization is required to achieve this response. Unlike designs that require equalization, the SSP218’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 SSP218 does not suffer from these limitations. It faithfully delivers the low bass where most others either roll off or die trying.

    Versatile and durable, the cabinet is finished in black textured weatherproof polyurethane coating. A top-mounted pole socket in each SSP218 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.

    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 DOES cover 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 SSP218 Subwoofer to levels and depths that would otherwise require more or bigger cabinets.

    Optional accessories – the Custom Fit Wheel Dolly allows for easy movement of one or two subs. Custom Made Protective Covers for One or a Stack of Two Subwoofers 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.
