Powerful speaker broadcast capability with minimal installation provision

AEM’s next-generation loudspeaker systems are a family of newly designed 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.

Developed to replace the 200W/PA220-based system, we designed and qualified the LSS440 system to meet the various operational roles of aircraft such as the MD530, R66, and EC120. The LSS440 delivers 440W of effective peak audio output power.
