d&b audiotechnik 27S-SUB

The 27S-SUB is a compact high performance cardioid subwoofer powered by a single amplifier channel and is for use with the xS-Series and xA-Series loudspeakers. The cabinet houses two long excursion neodymium drivers in an integrated cardioid setup: a 15“ driver in a bass-reflex design facing to the front and a 12” driver in a two chamber bandpass design radiating to the rear. 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) opt...ion that can be executed in all RAL colours, whilst the Weather Resistant (WR) option provides an IP34 rating, and enables operation of loudspeakers in changing ambient conditions.
