The cabinets are constructed from 18mm marine-grade Birch plywood. The cabinet is extensively braced
and construction features dado and rabbet joinery throughout, so all seams are interlocked and the cabinet
is ultra-rigid. 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 ports.
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. Waterproof mains connectors, along with a totally isolated input connection section and
cones that are waterproofed, make the MK3 series the powered loudspeakers that can be used outdoors
without fear of what the weather will bring. (Or used indoors without fear of what the partiers bring.)
Electrical power is converted into the much more desirable acoustical power by a very robust, neodymium
motor, 18-inch woofer with a massive 4.5-inch (115mm) voice coil. Neodymium magnets are lighter, and
their higher intensity provides higher eiciency, 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 high-pass and low-
pass filters, as well as a five-stage limiter system 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 dierent modes, the limiters are sophisticated enough to have a largely unnoticable eect 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. Each cabinet includes a two-port switch so multiple cabinets can
be chained on the same data cable 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.
The MK3 DSP features storage capacity for 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 BASSBOSS
tops and subs.
