2.1. Product description
The 12S and 12S-D are high performance 2-way loudspeakers
employing a single 12” neodymium driver in a bass-reflex
enclosure and different HF sections for a wide range of installed
sound applications. Both models are lightweight passive designs
using a 1.4” exit neodymium driver and large horns for accurate
pattern control. They provide rotatable dispersion characteristics of
75° x 50° (12S) or 110° x 55° (12S-D).
With a frequency response extending from 48 Hz to 18 kHz, the
cabinets can be used as full range systems or supplemented by
different subwoofers of the xS- or xA-Series.
The enclosures are constructed from marine plywood with an
impact resistant black paint finish. The fronts of the cabinets are
protected by a rigid metal grill backed by an acoustically
transparent foam.
The cabinets are Ball Impact Resistant according to DIN 18032-3.
Rigging components
The 12S rear panels incorporate two M8 threaded inserts to
accept the Z5406 12S Flying bracket or the Z5402 Wall mount
M or Z5403 Wall mount L.
Top and bottom panels of the cabinets are each equipped with a
pair of M10 threads to connect to different rigging accessories
such as Z5411 Horizontal bracket 12S, Z5354 E8/E12 Flying
adapter or Z5020/25 Flying adapter 02/03. The M10 threads
are covered by dummy caps in cabinet color. The caps must be
removed before mounting any accessories.
