The LCH70T is one of the latest products from ATEIS INTERNATIONAL and especially designed for the voice-evacuation market. The LCH70T is a typical exponential horn that is designed to be used in placed with restricted ceiling heights and where far throws are requested. The LCH70T is made of reinforced fiber/epoxy and equipped with a strong and powerful 2" compression driver, capable of producing a fabulous 117 dB. The shape and structure allow for use in highly demanding environments like traffic tunnels and car parks. Also train tubes that need to be addressed during voice-evacuations are typical examples where the LCH70T would fit perfectly. Due to its dimensions, its throw can reach from 40m up to 70m, reducing amplifiers and delay lines when compared to conventional distributed sound systems for tunnels.
