MARTIN AUDIO B218X

The B218X enclosure is constructed from plywood and finished in black textured paint.

For added versatility in deployment, the B218X is fitted with a 35mm pole-mount socket for mounting 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 B218X 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 B218X is supplied as standard without castors, which are available as an accessory pack.

When used with full-range systems, crossover and EQ functions can be performed by the DX0.4, DX0.6 or DX4.0 system controllers or by a Martin Audio amplifier with onboard DSP.
