Vented single 18 in. direct radiator subwoofer. 2500W RMS amplifier, integrated, comprehensive DSP. ±3dB: 30 - 100 Hz.
The SSP118-MK3 Single 18” Powered Subwoofer gives you low frequency output to 30 Hz,
typical of an average Single 18”, from a single 18” box. Delivering output to frequencies lower
than many Single 18” cabinets, each individual SSP118-MK3 does so in about half the space
and considerably less weight. This is a very practical consideration from both a size and cost
point of view.
For Mobile Professionals who provide superior sound quality, the SSP118-MK3 allows you to deliver premium service with less equipment and labor. With two SSP118-MKII Subwoofers, you will have the output of one of the worlds finest Single-18” subwoofers, the BASSBOSS SSP218, divided into two smaller, more manageable pieces.
The cabinets are constructed from 18mm Baltic Birch plywood. Each cabinet features dado and rabbet joinery throughout, so all seams are extremely strong and long-lasting. Stainless steel bolts are used to secure the drivers, amplifier and pole sockets so that the fasteners will never rust or seize up. The cabinet is finished in an extremely rugged, black polyurea coating and the driver is protected by a black powder-coated, perforated steel grille.
The SSP118-MK3 features a 2500W amplifier with an auto-sensing, globally compatible power supply that can run on mains supplies anywhere between 90 and 250 Volts. Full output power is available on anything over 110V. The amplifier’s high peak-output voltage provides for intense high SPL hits while its sustained output is unparalleled in its ability to deliver the liquid lows. The amplifier is passively cooled via its external heat-sink and by woofer-generated air-flow through the port. When necessary, two blower-fans will engage to provide additional forced-air cooling capacity in more extreme conditions
New to the MK3 are Neutrik powerCON True 1 TOP (Total Outdoor Protection) waterproof mains connectors. This permits the levels of multiple loudspeakers to be adjusted together and yet independently from the levels of other groups of loudspeakers.
Electrical power is converted into the much more desirable acoustical power by two robust, neodymium motor, 18-inch woofers with massive 4.5-inch (115mm) voice coils. Neodymium magnets are lighter, and their higher intensity provides higher efficiency, so the result is a lighter and louder cabinet than those with ferrite drivers.
The MK3 features an all-new DSP. The comprehensive suite of processing includes highpass and low-pass filters as well as multiple protection systems and limiters to prevent driver overload in as many ways as possible, including thermal, excursion and clipping. The five levels of protection actively prevent overheating of the voice coil, minimize long-term thermal compression and limit excursion. Because they operate in 5 different modes, the limiters are sophisticated enough to have a largely unnoticable effect on the transient response and allow the subwoofer to deliver peak output safely.
The new DSP features an Ethernet interface. This can be used to control the cabinets from a computer or to load software or firmware updates. The ethernet connectivity in conjunction with the DSP board allows signal to be sent via Milan AVB. Firmware updates will provide access to this feature.
Within the software, multiple cabinets can be grouped together, allowing them to respond to commands simultaneously. This permits the levels of multiple loudspeakers to be adjusted together and yet independently from the levels of other groups of loudspeakers. In addition to individual and grouped level controls, presets can be loaded and signal levels and temperatures can be monitored. Each cabinet includes a two-port switch so multiple cabinets can be chained on the same data cable.
The MK3 DSP features storage capacity of up to 100 presets, eight of which can be accessed at the touch of a button with no need for a connected computer. The eight directly accessible presets are compatible with all the presets in the MK3 Top Boxes and are also compatible with previous generation tops and subs.
