Martin Audio Blackline XP118 Powered Subwoofer

The Martin Audio Blackline XP118 is a compact, self-powered subwoofer designed to deliver deep, impactful bass in a variety of professional audio applications. It features an 18” (460mm) long-excursion driver with a 4” (100mm) voice coil, housed in a durable birch/poplar plywood enclosure finished with black textured paint. The enclosure includes a screw-free, perforated steel grille and two ergonomic side handles for ease of transport.

Powered by a 2000W Class D amplifier with onboard DSP, the XP118 offers a frequency response of 42Hz – 150Hz ±3dB and a maximum SPL of 137dB peak (half space). The DSP provides 3-band input channel EQ, 4 speaker EQ presets (including cardioid mode), and protection features such as peak and RMS limiting and amplifier thermal protection. Control and monitoring are facilitated via a multi-function display and rotary encoder interface on the rear panel.

Connectivity options include two female XLR/1⁄4” jack combo inputs, a male XLR mix output, and a 35mm pole-mount socket for satellite speakers. The XP118 can be used singly, stacked in omni or cardioid mode, or flown via integral M10 inserts, making it versatile for various setups. Its compact dimensions (662mm x 536mm x 640mm) and weight (44kg) make it suitable for both portable and installed applications.

Ideal for use with the Blackline XP12, the XP118 extends the low-frequency operating range of the combined system down to 42Hz, providing exceptional low-frequency impact. Its applications include portable sound reinforcement, live music clubs, nightclubs, bars and restaurants, corporate AV events, hotels and casinos, mobile DJs, weddings and parties, houses of worship, and rehearsal studios.
