ATEIS - LCS70T INDUSTRIAL LOW CEILING HORN Ateis-LCS70T

The LCS70T is an exponential horn that is designed to be used in applications where restricted ceiling heights, high intelligibility and long throw is required.

The LCS70T is made of reinforced fibre/epoxy and equipped with a strong and powerful 2 compression driver, capable of producing 117 dB. The shape and structure allows 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 LCS70T would fit perfectly.

Due to its dimensions, its throw can reach from 40 to 70m, reducing amplifiers and delay lines when compared to conventional distributed sound systems for tunnels. This will bring the total costs down and due to a lower number of horns, it will bring the Q-factor up and so the intelligibility of the overall evacuation system.

The LCS70T has an extended frequency range that runs up to 8 kHz allowing for high-fidelity speech messages in situation where the acoustics are limited and therefore the demands on the sound system high. Highly directional horns will result in a bigger in between, repeating distance, reduced sound-points and so reduced number of amplifiers and delay-lines and so, resulting in a better overall price performance.

The LCS70T is a typical symmetrical exponential horn (= where the horn length is exponentially related to the horn area) that uses the mounting surface as wave guide. This way a half cell construction can be used, reducing its mouth height that is important when used in environment with height restrictions. Once in the proper band pass region for a given size, an exponential horn presents a fairly consistent acoustical load to its driver. This helps both output level and evenness of frequency response, and is what makes this horn design simple and effective.
