The Reflex B218 is a high-power sub bass enclosure designed to operate over the 34 – 95 Hz pass band. The B218 is the recommended sub bass element for Optima array systems, within the live sound and touring market. Alternatively, it can be combined with products from the MQ and Vector product ranges and is equally suited to use within fixed installation projects.

The enclosure contains dual 18” long excursion cone drivers with neodymium magnet structure and 100 mm split wound voice coils to enable very large excursion limits. This is loaded into a dual cavity direct radiating, vented and cross braced enclosure which is manufactured from 18mm birch plywood and coated in a heavy duty polyurea finish. The cabinet front has a protective steel grill coated in a water-resistant powder coat finish which has an acoustically transparent filter medium bonded to its back surface. Each cabinet has four pairs of steel bar handles fitted to the side, top and bottom panels. The cabinet back panel has the option of being fitted with castors to aid mobility. The cabinet base has polyethylene runners and the cabinet top panel housings to ensure secure stacking of cabinets in vertical columns. The top panel also has additional housing that permit Reflex B118 cabinets to be stacked in pairs.
