4. X18WE FEATURES

The X18WE cabinet is ideal for bass reinforcement in general and specifically in

combination with models X12CE, X15CE and X15LTE. It includes 2400W

amplification for the woofer and digital signal control by DSP. The manufacturer

presets (LPF90+3, LPF90+6, LPF110+3, LPF110+6, LPF130+3, LPF130+6,

CARDIOID) make it easy, flexible and user-friendly.

The 18” neodymium woofer used, thanks to its exclusive magnetic design, combines

excellent bass frequency response, high performance and low distortion. These

features are mainly due to the presence of demodulation rings which drastically

reduce the inter-modulation and third order distortion and considerably improve the

transitory response. There is excellent heat dissipation due to the external positioning

of the magnet set. Without any doubt one of the finest bass transducers currently

available. The result is a clean, high quality sound.

The upper surface incorporates a pole mount socket for a standard 35mm bar.

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.
