The DJ18-MK3 is a premium-quality subwoofer which delivers deep bass at levels far higher
than would be expected from its size. Suitable for the truly bass-insatiable who focus on
modern music with frequencies well below the usual 50-100Hz range, this compact sub
weighs only 110 lbs and delivers output down to 27Hz (-3dB).
The DJ18-MK3 is a single 18-inch direct-radiating subwoofer featuring a long-excursion
woofer loaded into a vented enclosure that is tuned to optimize extremely low frequency
output using a very large port. The cabinet was designed to minimize materials and weight
and maximize efficiency. The point is to do less heavy lifting and deliver more heavy bass.
The DJ18-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 woofergenerated 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. 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 robust,
neodymium motor, 18-inch woofer with a massive 4.5-inch (115mm) copper-wound voice coil.
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.
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.

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.
