zZounds Gear Experts Say...

With BASSBOSS's MK3 amplifier pushing 5000 watts through two 18" speakers with beefy 4" voice coils in a birch box, this is one truly high-performance sub!

Overview

The active SSP218-MK3 provides Super High Output, extended deep bass, exceptional sound quality, massive power, unbeatable reliability, and an incredible value in all realms.

Delivering massive, extremely flat response that is +/- 1.5dB from 32Hz to 100Hz, the SSP218-MK3 yields consistency and great fidelity across all modern electronic, jazz, reggae, pop, country, rock, regional, acoustical, and R&B music with accuracy, physicality, and ease.

Incorporating innovative technologies into the rigidly braced vented cabinets, the SSP218-MK3 is optimized to operate at sustained full rated RMS power throughout its operating range while the woofers remain within their X-max specification ensuring it delivers, day in and day out, in the touring and installed worlds. This workhorse 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 state of the art DSP.

The MK3 series delivers a suite of updates to the BASSBOSS line, improving clarity, performance, functionality, and safety via amplifiers, DSP, custom control software, waterproof connectors, and more.

The updated amplifiers + DSP feature much more powerful 96 kHz processors with pristine sound quality and eight touch-of-a-button on board presets.

The state-of-the-art Class D amplifier provides a true 5000 Watts of RMS power. The amplifier is truly capable of delivering continuous power, ensuring that… read more it isn't the limiting factor on your quest for low frequency. Additionally, by providing an abundance of power, the possibility of overheating and damage to the woofers caused by clipping is virtually eliminated.

"Control BASSBOSS" software provides additional computer-accessible presets, networked remote control, and future proofing remote DSP update capabilities as BASSBOSS programming is developed and released. Each unit features dual ethernet ports with a built-in network switch for computer connectivity and cascading networking ability.

IP65 waterproof connectors have been added to provide peace-of-mind in unpredictable environments, and the MK3 line offers 90-250VAC global power compatibility for use all over the world.

Versatile and durable, the Baltic Birch flyable cabinet is finished in black textured weatherproof polyurethane coating. A top-mounted pole socket in each SSP218-MK3 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. Additionally, physical dimensions were carefully crafted to create the ideal truck-pack.

This pinnacle subwoofer 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. From Touring to Night Club Installations, the BASSBOSS SSP218 lineage has served as the cornerstone for powered double 18s for decades of revered success.

True Specifications
BASSBOSS have stopped using "Peak" and "RMS" power ratings for their amplifiers because those numbers alone are not an accurate representation of the real-world performance you can expect from their powered loudspeaker systems.

Peak Watts: Essentially a theoretical maximum that the amplifiers could output for an instantaneous moment under ideal conditions with no load. However, this peak power is not sustainable and has little practical relevance for how the loudspeakers will actually perform.

RMS (root mean square) Watts: A measure of continuous power output, but even this figure doesn't account for the true efficiency of how that power is converted into acoustic output by the transducers and overall speaker design. The number of watts a loudspeaker "uses" is constantly fluctuating based on the impedance curve, frequency response, and heat generated in the voice coils. Simply looking at how many watts an amplifier can produce on a test bench doesn't translate to its real-world sound output capability.

What matters most is the complete integrated loudspeaker system and how efficiently it can convert the amplifier's power into acoustic output while maintaining flat frequency response and headroom. Two loudspeakers with the same wattage ratings could have vastly different real-world sound pressure levels and clarity.

For these reasons, BASSBOSS believes wattage ratings alone are not a reliable metric. Listening tests and measurements of the overall system's output capabilities like maximum SPL and distortion are far more telling than any peak or RMS wattage number viewed in isolation. The BASSBOSS goal is to provide outstanding performance through intelligent system design, not just big wattage numbers.
