The SLA Family of passive frequency shaded line arrays has been developed to provide a defined 25º V x 120° H coverage pattern with very uniform frequency response. Packaged in a slim profile, they supply excellent speech intelligibility and fidelity in acoustically challenging spaces.

The SLA-Micro Frequency Shaded Line Array loudspeaker employs a high frequency array of four 20mm drivers, in conjunction with eight 2” extended range drivers, all within an ultra-slim enclosure. It is designed to work in highly reverberant environments where very broad uniform horizontal coverage and a focused vertical pattern are beneficial.
