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.
