4.1. Technical description
The X18WE cabinet comes with DSP control, with direct radiation transducer and
acoustic bass reflex cabinet. As a bass reinforcement system, its frequency response
is 35Hz-130Hz (+/- 3dB) with a usable bandwidth between 30Hz-140Hz (-10dB).
It has 2000W continuous amplification, thermal protection, output short circuit
protection, maximum power limiters for each channel, and protection against
overvoltage. The DSP includes 7 presets which can be selected either accessing the
cabinet's rear control panel or via the computer with Ethernet connection. The
LPF90+3 preset means low pass filter at 90Hz and +3dB boost at 50Hz; LPF90+6
means low pass filter at 90Hz and +6dB boost at 50Hz; LPF110+3 means low pass
filter at 110Hz and +3dB boost at 50Hz; LPF110+6 means low pass filter at 110Hz
and +6dB boost at 50Hz; LPF130+3 means low pass filter at 130Hz and +3dB boost
at 50Hz; LPF130+6 means low pass filter at 130Hz and +6dB boost at 50Hz and
CARDIOID means cardioid polar pattern when used in combination with two other
X18WE subwoofers.
By upping the low pass filter a greater 'boom' sensation can be achieved, but clarity is
lost. It is down to the user to decide on the most suitable preset.
The X18WE is connected using the XLR balanced connectors. Mains supply is
through PowerCon at 230V.
It is built in birch plywood, which has a high resistance to vibrations and humidity with
black Polyurea paint finish. The front face is protected by a 1.5 mm thick steel grille
with acoustically transparent grey cloth.
