2.1. Product description
The 24S and 24S-D are high performance 2-way loudspeakers
employing two 12" neodymium LF 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 (h x v)
75° x 45° (24S) or 110° x 45° (24S-D).
The two 12" LF drivers are positioned in a dipolar arrangement
providing exceptional vertical dispersion control even at lower
frequencies.
Specially designed ports with optimized flow characteristics
provide a considerably improved, efficient low frequency
reproduction.
With a frequency response extending from 55 Hz to above
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 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.
Cabinet options
The weather resistant version (WR) is suitable for outdoor use
(IP34, vertical aiming up to +15°). The cabinets have an impact
and weather protected black PCP (Polyurea Cabinet Protection)
finish.
