The two-way full range loudspeaker systems shall incorpo- rate eight 4-in LF transducers and three 1-in soft dome tweeter HF transducer.

All eleven drivers shall be mounted in a vertical column to create a line source. The LF drivers shall be mounted four each above and below the three HF drivers. An internal fre- quency shading filter set shall maximize beneficial line source coupling while minimizing grading lobes. An internal pas- sive filter network shall provide fourth order acoustical cross- over and system equalization between the low and high fre- quency sections.

System frequency response shall vary no more than ±3 dB from 200 Hz to 20 kHz 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 126.0 dB SPL on axis at 1 meter. The system shall handle 200 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 12 Ohms.

The loudspeaker enclosure shall be rectangular in shape with a convex arc to the front baffle. It shall be constructed of 15mm thickness void-free cross-grain-laminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed polyurethane. Input connec- tors shall be two-terminal barrier strip. A total of 6x 1/4"-20 threaded mounting/suspension points (1 each top, bottom, 4 back) shall be provided. The front of the loudspeaker shall be covered with a vinyl coated perforated steel grill.

The 2-way full range loudspeaker shall be the EAW model LS832.
