AT-SMA-LCS70T
The LCS70T is one of the latest products from ATEÏS and especially designed for the voice-evacuation market. The LCS70T is a typical exponential horn that is designed to be used in placed with restricted ceiling heights and where far throws are requested.The LCS70Tis 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 LCS70T would fit perfectly. Due to its dimensions, its throw can reach from 40 up to 70 m, 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. The LCS70T should be fixed against a large and flat surface that acts as a waveguide and mirror. The small horizontal opening angle of only 30 degrees guarantees that the sound will stay unaffected by lateral distortion and so will increases the in-between distance of the horns.

AT-SMA-SMARTVOX-MA12
SMARTVOX-MA12 is a vertical loudspeaker array that uses a linear spaced speaker arrangement in combination with passive phase shifting, passive power shading and filtering, to obtain a constant directivity index for multiple frequencies (Concept is based on the MESSENGER linear spaced line-arrays with patent algorithm). The fixed Azimuth angle of -12 degrees, allows for the unit to be placed vertical against any surface, resulting in more clarity, lower reverberant field and therefore a much higher ‘direct-to-reverb’ ratio, leading to a higher intelligibility figure (STI).Ordinary line-arrays radiate a cylindrical wave front that moves in a straight line from its source. Due to this a normal column needs to be tilted forward to obtain good coverage of the listening area (picture1).This is needed to focus the sound waves in forward direction into the audience area trying to avoid annoying reflections from other surfaces. Loudspeakers in general are not only producing sound forwards but also backwards especially for the lower frequencies. These sound waves are reflected by the back wall to which the array is fixed. These waves are mirrored according to the mounting angle of the array and will fill the environment with un-wanted artificial reverberation energy, leading to lower direct-to-reverb ratio and to a poor intelligibility. By ”aiming” the beam of a loudspeaker electronically using passive phase-shifting, power-shading and filtering technique for constant directivity, you can keep the column perfectly vertical position against (picture2)  its surface reducing any additional attributed energy to the reverberant field, resulting in more clarity and a much higher intelligibility. The Smartvox-MA12 distinguishes itself through its precise sound direction pattern in the vertical plane, independent of the frequency. Due to constant sound pressure over long distances fewer columns are needed, which makes the installation far more simple and effective.

BO-XLA-LBC3201/00
This loudspeaker, with its excellent directivity and high power output, can handle medium and large (reverberant) indoor environments, especially the more acoustically challenging ones. It is typically used in congress venues, meeting halls and places of worship. The full frequency range of the LBC 3201/00 makes it ideal for speech as well as music reproduction. Its exceptionally narrow housing (only 8 cm wide) makes it extremely unobtrusive.
