The low frequency loudspeaker system shall incorporate a 15in LF transducer that shall be mounted in a vented enclosure tuned for optimum LF response.
System frequency response shall vary no more than ±3 dB from 60 to 500 Hz measured on axis. The system shall produce a Sound Pressure Level (SPL) of 97 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 130 dB SPL on axis at 1 meter. The system shall handle 600 Watts of amplifier power (continuous) and shall have a nominal impedance of 8 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of multi-ply, void-free, cross-grain-laminated, exterior grade, Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in wear-resistant textured black paint. Input connectors shall be 2-contact terminal strip. Eighteen (18) 3/8"-16 threaded mounting/suspension points (4 each top, bottom and sides, 2 on back) shall be provided. The front of the loudspeaker shall be covered with a powder coated perforated steel grille.
The low frequency loudspeaker shall be the DECO model AS415i
