LSS440
Loudspeaker System

Product

Over 400W of effective, peak audio output power.

AEM’s loudspeaker systems are a family of Loudspeakers (LS), Loudspeaker Amplifiers (LSA), and Loudspeaker Controllers (LSC) delivering fantastic sound quality and power output in a lighter, smaller, and less expensive package than comparable systems on the market today.

We designed and qualified the LSS440 system to meet the operational roles of both current and future, light and medium turbine helicopters, such as the B206, EC120, AW119, and UH-1.
