Martin Audio Blackline XP118 18" Powered Subwoofer

XP118 is the powered subwoofer that finishes a BlacklineX system. A long-excursion 18" ferrite driver in a compact reflex cabinet, driven by a bridged class D module at 2000W peak, reaches 42Hz within 3dB and 137dB peak in half space, which is enough to put weight under a DJ set or a live band in a mid-size room.

Setup is deliberately short. Two speaker EQ presets are built in, one for XP118 with XP12 and one for XP118 with XP15, and the 100Hz active crossover is already set, so plugging tops into the mix output and picking the preset is the whole alignment process. Inputs are two combo XLR and 1/4" jack sockets with three-band EQ, and there is a male XLR mix output. Sixteen M10 inserts, a pole-mount socket, two bar handles and provision for castors cover deployment. Mains input is 100 to 240V AC with power factor correction.
