LHS41
Loudspeaker System

Product

Drives 142 dB of SPL and intelligibly clear audio at long range.

The Loud Hailer System (LHS) is AEM's newest in loudspeaker system technology. Building upon the successes and high performance of AEM's existing family of loudspeaker systems, the LHS41 delivers unmatched audio quality and Sound Pressure Level (SPL) output from an impressively efficient and relatively compact mechanical package.

The LHS41 is capable of generating decibels louder than the active flight deck of an aircraft carrier, and louder than a freight train passing by when the systems is broadcasting air-to-ground at a distance of 1,000 meters (1km).

Made up of the LS800-34DT (Loudspeaker), LSA800-002 (Amplifier) and LSC22-10xN (Controller), the LHS41 produces 142 dB with extremely low distortion levels and a full system weight at a lean 36.6 lb (MAX). As a result of efficient Direct Drive loudspeaker drivers, the LHS41 requires only 800W peak output power to produce AEM's loudest and clearest system to date.  

The LHS41 is designed and qualified to fully meet the operational special roles of both super medium and heavy rotary wing aircraft.

*AEM's LHS41 is a full system made up of the LS800-34DT, LSA800-002 and LSC22-10xN. These products are not meant to be cross-compatible with other AEM loudspeaker system products.
