GSL8 Architectural specifications

The loudspeaker system shall consist of two forward 14" LF neodymium drivers in a vented enclosure radiating to the front, two sideward 10" LF neodymium drivers, one hornloaded 10" midrange driver and three coaxially mounted 1.4" exit compression drivers with 3.4” voicecoils coupled to a waveshaping device.
The loudspeaker system shall be 3-way, actively driven between the forward LF drivers and the sideward LF driver with mid/high sections. Passive crossovers shall be used between the sideward LF driver and the mid/high sections.
The loudspeaker shall only be operated by a dedicated, compatible controller amplifier.
The loudspeaker shall produce a cylindrical wave segment suitable for use as an element in a line array and maintain an extremely accurate horizontal dispersion pattern of 80° down to 150 Hz merging into a cardioid dispersion down to the lowest frequency.
The enclosure shall be constructed from marine plywood with an impact resistant and weather protecting PCP (Polyurea Cabinet Protection) finish. The cabinet front and side shall be protected by a perforated steel grill backed with acoustically transparent and water repellent fabric.
The cabinet shall incorporate a three point rigging system for the assembly of vertical line source arrays of up to 24 cabinets in connection with a dedicated flying frame.
The power handling of the forward LF section shall be 800/3200 W (RMS/peak 10 ms) while the power handling of the sideward LF drivers and MF/HF section shall be 800/3200 W (RMS/peak 10 ms).
The frequency response (–5 dB) measured on axis shall extend from 45 Hz - 18 kHz with maximum sound pressure level (SPLmax peak/1 m) of at least 150 dB. The horizontal dispersion shall be 80°, while the vertical splay angle shall be adjustable in a range of 0° - 7° in 1° increments.
The connection panel on the back shall be recessed and fitted with one speakON NLT4 F socket.
The dimensions (W x H x D) shall not exceed 1300 x 391 x 627 mm (51.2" x 15.4" x 24.7") and shall weigh no more than 80 kg (176 lb).

The loudspeaker shall be the GSL8 by: d&b audiotechnik GmbH & Co. KG.
