d&b 8S - Manual (Page 5)

2.1. Product description
The 8S loudspeaker is a full range, two-way bass-reflex enclosure,
utilizing an 8"/1" coaxial driver combination with a passive
crossover. Coaxially mounting the 1" HF compression driver and
8" LF driver using a single magnet assembly creates a very
compact driver with 100° constant directivity HF dispersion.
With a frequency response extending from 70 Hz to 20 kHz, the
cabinet can be used as a full range system or supplemented by
different subwoofers of the xS- or xA-Series.
The enclosure is constructed from marine plywood with an impact
resistant black paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill backed by an acoustically
transparent foam
The 8S rear panel incorporates two M8 threaded inserts to accept
the Z5402 Wall mount M, the Z5403 Wall mount L or the Z5404
Flying bracket 8S. The top and bottom panels are each equipped
with an M8 thread to accept the Z5408 Horizontal bracket 8S.
The threads are covered by dummy caps in cabinet color. The caps
must be removed before mounting any accessories.
