Description

The X218 enclosure is constructed from plywood and finished in black textured paint as standard, with white and RAL colour finishes available to special order.

For added versatility in deployment, the X218 is fitted with a 35mm pole-mount socket for mounting BlacklineX full-range enclosures, and integral M10 inserts provide for eyebolt suspension of a single enclosure. Ergonomic handles assist ease of handling and the drivers are protected by a perforated steel grille. Rubber feet on the base of the X218 resist movement and align with recesses in the top surface for stable horizontal stacking. Feet are also provided on one side of the enclosure for vertical operation of a single cabinet.

The X218 is supplied as standard without castors, which are available as an accessory pack.

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.
