Martin Audio XP118 Backline 1 x 18-Inch Subwoofer

The XP118 is a compact, high-performance subwoofer for indoor use with the XP12 and XP15 full-range loudspeakers. It extends the low frequency operating range of the combined system down to 42Hz and can be used singly, stacked in omni or cardioid mode, or flown via integral M10 insets.

Featuring a long-excursion 18” (460mm)/4” (100mm) voice coil driver in a compact enclosure that has four reflex ports with a large frontal area to reduce turbulent air noise at very high levels.

A convection-cooled Class D amplifier module delivers 2000W peak output to the driver for maximum low frequency extension and chest-thumping punch. Crossover, EQ, metering and

control functions are provided by onboard DSP via a rotary encoder interface and multi-function colour screen on the rear panel.
The XP118 enclosure is built for the road, constructed from durable plywood and finished in textured black paint. A perforated steel grille protects the driver, and the enclosure has a 35mm pole-mount socket in the top surface and two ergonomic side handles.
