The d&b audiotechnik 18S-SUB is a compact subwoofer with an 18″ neodymium driver in an impact resistant, bass-reflex cabinet with rubber feet for stacking protection and side-panel bracket threads for flown installation
The 18S-SUB is a compact, flyable subwoofer built for use with d&b audiotechnik xS-Series and xA-Series loudspeakers. A high-performance, 1,600W (peak) design with a maximum SPL of 132dB, the 18S-SUB cabinet houses a long-excursion, 18″ neodymium driver in a bass-reflex design. It can be used in stand-alone, stacked, or as a base for a mixed ground stack. While the d&b 18S-SUB and 18A-SUB share the same internal components and specifications, the distinguishing factor is that the 18A can also be combined with 10A and 10AL loudspeakers in vertical flown arrays. The enclosure of the 18S-SUB 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 18S-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 M10 threads for horizontal brackets, 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.
18S-SUB rigging components
The 18S-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 18S-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.
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 18S-SUB. The d&b D20, D80, 10D, and D6 can also be used.
