Product description

The 18S-SUB is a compact high performance subwoofer for use with the xS-Series and xA-Series loudspeakers. The cabinet houses a long excursion 18" neodymium driver in a bass-reflex design and it can be used stand-alone, stacked or individually flown. The enclosure is constructed from marine plywood with an impact resistant black paint finish and is Ball Impact Resistant according to DIN 18032-3 for schools and sports halls. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent foam. Incorporated into the side panels are a pair of M10 threaded inserts and into the rear panel are two NL4 connectors as well as a two pole screw terminal block. The loudspeaker cabinets and most accessories are also available with the Special Colour (SC) option that can be executed in all RAL colours, whilst the Weather Resistant (WR) option provides an IP55 rating, and enables operation of loudspeakers in changing ambient conditions.
