Compact Loudspeaker System


Suited for aircraft such as the R44, 480B, B206, and AT-802.

AEM designed the LSS220 Compact Loudspeaker System for light aircraft—such as small turbine helicopters and fire-fighting aircraft—where a siren is the priority requirement.

Designed to replace the 100W/PA110-based system, the LSS220’s use of new-generation parts and automated electronic assembly make this an affordable package that will outperform any comparable system on the market today. Utilize this power-efficient system for applications with a typical target distance of 200-300 feet at ground level.

The LSS220 system is suited for aircraft such as the R44, 480B, B206, and AT-802; it delivers 220W of effective peak audio output power.
