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.
