d&b audiotechnik 24S-D Loudspeaker

Featuring d&b audiotechnik’s belief that everyone should experience the same impeccable sound quality, regardless of position in the audience, the high-performance 24S-D is a full-range, 2-way passive loudspeaker with two 12″ drivers in a bass-reflex enclosure. The 24S-D also has a 1.4″ exit compression driver mounted onto a large rotatable constant directivity (CD) horn. The point-source 24-S-D is designed to handle a wide range of applications for fixed installations. It has a wider horizontal dispersion than its counterpart, the 24S loudspeaker. The dipolar arrangement of the 12″ drivers results in directivity control down to approximately 500Hz in the same plane as the dipole. The specially designed ports with optimized flow characteristics and a large cabinet volume provide a significant low-frequency reproduction. With a frequency response extending from 55Hz to 18kHz, the 24S-D can be used as a stand-alone, full-range system, or supplemented with d&b subwoofers. It can be ground stacked or flown individually. Additionally, its high-frequency horn can be rotated by 90° for horizontal orientation.

d&b audiotechnik 24S-D—Parsing the Details:

The loudspeaker cabinet is constructed from marine plywood and has an impact-resistant paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill. The top, bottom, and both side panels each incorporate a pair of M10 threaded inserts for attaching d&b rigging hardware. The loudspeakers are Ball Impact Resistant according to DIN 18032-3 for sports and multipurpose halls. The Weather Resistant option (WR) option provides an IP55* rating, enabling long-term use in changing ambient conditions, and features a fixed cable. The 24S-D can also be supplied in any RAL* color. This special color option can be provided for rigging accessories.

**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. 

**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. 

Recommended amplifiers

The four-channel, 800W (@ 8 ohms) d&b 30D amplifier is recommended to drive the 24S-D in applications where medium to high sound pressure level (SPL) capabilities are called for. The d&b D20 and D80 power amplifiers can also be used.

24S applications

• Music and live program reinforcement for permanent installations
• Live-performance venues
• Night clubs
• Houses of Worship
• Sporting venues
• Multipurpose suites
