DSX / DSX-F

MLA Compact deserves a subwoofer that can match its performance. With an extremely high output level, compact size and
advanced DSP-based realisation of directional arrays, the DSX more than meets this challenge.
Capable of 146dB peak output at 1m (half space, measured), the DSX powered and networked subwoofer is an incredible
performer. Its high output level is achieved by combining state-of-the-art LF driver technology with an on-board Class D amplifier
module which can deliver 6kW peak power.
The DSX features 2 × 18"(450mm)/4"(100m) voice coil, ferrite drivers in a reflex-loaded enclosure with four flared ports, carefully
designed to improve linear airflow. Each driver is housed in its own separate chamber to move any cabinet resonances out of
band. Sonically, the DSX is a perfect balance of low frequency extension and punch.

Mechanical Design

The MLX cabinet is constructed from 18 and 24mm birch plywood and is finished with a black textured PU coating. All metalwork
is powder coated steel with all exposed fixings high grade black stainless steel. Black nylon skids on the base locate easily into
routed slots on the top of the cabinet to give a positive lock aiding stability of ground stacked systems. Rubber locating skids on
the sides protect the cabinet and offer positive locating when stacking DSX up on end in trucks or back in the shop.
Every possible measure has been taken to make the sub as manageable as possible. It is supplied with heavy duty castors fitted
to the rear of the cabinet for transportation. Each side of the MLX has a strong bar handle running almost the full depth of the
cabinet making it easy for four crew to lift the cabinet with two at each side. A rugged canvas cover is supplied which has an
integral timber board which locates on the uppermost surface of the sub when it is on its castors. This protects the grill making
it completely safe to transport the MLX even with other equipment stacked on top of the MLX in the truck or back in the shop.
The DSX is designed to complement the MLA system and has been dimensioned accordingly. It is the same width and height as
an MLX but is not as deep. It is therefore the same width as an MLA and is flown using the same flying grid which has additional
drop-down bars to accommodate the shallower cabinet. Combination arrays of DSX-F and MLA Compact can be created using
the MLA flying grids at the top for the DSX-F and the Combination grid to link between the bottom DSX-F and first MLA Compact.
The cabinet is designed with cardioid arrays in mind and can easily be stacked or flown (DSX-F only) with a third of the DSX facing
backwards. The top of the cabinet features a channel down which all connecting cables are laid and there is a cable entry position
at the back so connections can be made and hidden by the hinged cover. There is also a hinged ventilation cover above the
connection panel which must be opened during operation.
