About this item



d&b audiotechnik 27S-SUB Compact Flyable Subwoofer

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 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, the rear panel incorporates two Neutrik NL4 speakON connectors and 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, while the Weather Resistant (WR) option provides an IP55* rating and enables the 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 and 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. 

Compatible amplifiers

The d&b amplifiers are designed specifically to power d&b loudspeakers, forming the heart of the d&b System. They incorporate digital signal processing for comprehensive loudspeaker management, switchable filter functions, remote capabilities, and user-definable controls to fulfill the exact needs of each application.

The d&b 30D amplifier is recommended to drive the 27S-SUB. The d&b D20, D80, 10D, and D6 can also be used.

27S-SUB applications:

  • Theater and Opera
  • Nightclubs and bars
  • Houses of Worship
  • Other (e.g. Spazio Gessi showroom and meeting center, Milan, Italy)
