architectural and engineering specifications
The loudspeaker system shall be of the two-way
switchable active/passive type consisting of one 12"
(300mm) direct radiating reflex loaded low frequency
transducer and one 1" (25mm) exit HF compression
driver mounted on a constant directivity horn in a
trapezoidal plywood enclosure. The enclosure shall be
fitted with an integral pole mounting socket and
threaded inserts to facilitate a variety of mounting
options. Active or passive operation shall be selected by
a switch at the rear of the enclosure. In active mode the
loudspeaker shall be bi-amped and operated with a
separate electronic controller. In passive mode, low and
high frequency sections shall be integrated by an
internal 2kHz passive crossover network.
