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.

(IP34, vertical aiming up to +15°). The cabinets have an impact

and weather protected black PCP (Polyurea Cabinet Protection)

finish.
