Martin Audio just launched the X218 subwoofer as part of the company’s BlacklineX series of speakers. BlacklineX is aimed at live events, corporate installs and houses of worship. The original line-up comprised just a 15″ and single 18″ subwoofer, while the new X218 is a dual-driver, high-performance subwoofer with an operating range of 42Hz-200Hz + 3dB. It produces high output levels –141dB peak SPL (half space) — with low distortion and can be used singly or stacked horizontally. It features dual 18″/4″ voice coil, long-excursion drivers in a reflex enclosure with eight large ports that reduce air turbulence at high output levels.
For versatility in deployment, the X218 is fitted with a 1 3/8-inch pole-mount socket for mounting BlacklineX full-range enclosures and integral M10 inserts provide for eyebolt suspension of a single enclosure.
When used with BlacklineX Series full-range systems, crossover and EQ functions can be performed by the DX0.5 or DX4.0 system controllers or by a Martin Audio amplifier with onboard DSP.
