The 21S subwoofer
The 21S-SUB is a high performance subwoofer for use with the xS-Series and xA-Series loudspeakers and is intended for a wide range of permanently installed applications. The large, specially shaped re ex port enables the 21S-SUB to achieve high Sound Pressure Levels from a cabinet with a small footprint.
When operated in INFRA mode, the 21S-SUB can be used to complement other d&b subwoofers by extending the frequency response of the system down to 33Hz. The 21S-SUB can ground stacked or own in either orientation. It can be own individually or in a cluster of two cabinets.
The enclosure is constructed from marine plywood with an impact resistant black paint nish. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent foam. The top, bottom and rear panels each incorporate a pair of M10 threaded inserts for attaching d&b rigging hardware.
The Weather Resistant option enables the operation of loudspeakers in changing ambient conditions, and features a xed cable. The 21S-SUB can also be supplied in any RAL colour. This Special Colour option can be provided for rigging accessories.
