Here is quick view of the frontal assault! This setup can make theater's sound weak. The system consists of four Klipsch Klipschorn's, a La Scala center, and Heresy side surrounds/rear effects. Bass is provided by dual Velodyne HGS-15 15" Servo's, loud and low. With efficiencies of 104db@ 1W it can get real loud, real easy and accuracy and detail are off the scale due to the horn loading.
