DESCRIPTION
The d&b audiotechnik 27S-SUB is a compact, flyable subwoofer with dual neodymium long-throw drivers in an impact resistant, bass-reflex cabinet with an integrated rigging system in the side panels.
The 27S-SUB is a compact, flyable subwoofer built for use with d&b audiotechnik xA-Series and xS-Series loudspeakers. A high-performance, 2,000W (peak) design with a maximum SPL of 132dB, 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 band-pass design radiating to the rear. It can be used in stand-alone, stacked, or as a base for a mixed ground stack. While the d&b 27S-SUB and 27A-SUB share the same internal components and specifications, the distinguishing factor is that the 27A can also be combined with 10A and 10AL loudspeakers in vertical flown arrays. The 27S 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, sports arenas, and multipurpose halls.

D&B AUDIOTECHNIK 27S-SUB—PARSING THE DETAILS
The front of the loudspeaker cabinet is protected by a rigid metal grille backed by an acoustically transparent foam. The side panels have an integrated rigging system and the rear panel incorporates two Neutrik NL4 speakON connectors, as well as a two-pole screw terminal block. The loudspeaker cabinets and most accessories are also available with the Special Color (SC) option that can be executed in all RAL* colors, whilst the Weather Resistant (WR) option provides an IP55* rating, and enables operation of loudspeakers in changing ambient conditions.
*RAL is a color-matching system that defines standard colors for varnish, powder coating, and plastics. It’s the most popular Central European color standard used today.
**The IP Code or International Protection Rating, sometimes also interpreted as Ingress Protection Rating. IP55: Protected from limited dust ingress. Protected from low-pressure water jets from any direction.
27S-SUB-SUB rigging components
The 27S-SUB side panels are each equipped with a pair of M10 threads to accept the Z5410 Horizontal bracket (18S/27S). The threaded inserts are covered by dummy caps in cabinet color. (The caps must be removed before mounting any accessories.) For use as a base, the 27S-SUB is equipped with four rubber feet to prevent cabinet movement and protect the bottom panel against scratching. The cabinet is Ball-Impact Resistant according to DIN 18032-3.
