The biggest challenge facing a sound system designer is devising a system which will have a high direct to reverberant sound ratio, maximizing the sound that arrives directly to the listeners ear, while reducing the sound energy from walls, ceilings and other acoustically reflective surfaces. With the Intellivox DDC (Digital Directivity Control), DDS (Digital Directivity Synthesis) technologies, and WinControl software it's possible to control the vertical directivity pattern of Intellivox products and aim the sound where you want it - at the listener.
The standard Intellivox DC and DS column speakers are 134mm wide, 92 mm deep and available in 6 lengths. 1150mm, 1800mm, 2800mm, 3800mm, 4300mm and 5000mm. The longer the array, the more control you have over the directivity. They each have an array of 4 inch drivers with built in amplification and DSP. The DC/DS 115 has 2 additional tweeters to extend the frequency range.
The Intellivox DSX products have the same dimensions as their DC/DS equivalent, and include a small horn array, extending the frequency response to 18 kHz.
