LINE ARRAY DRIVER
KEY FEATURES
This combination of high power neodymium compression driver with wave guide gives a straightforward solution to build a Line
Array System, solving the difficult problem of achieving an optimum coupling between adjacent high frequency transducers.
Instead of using expensive and complicated wave-shaping devices, a simple but effective wave guide transforms the circular
aperture of the compression driver into a rectangular surface, without excessive angle aperture to provide low curvature to the
acoustic wavefront, arriving to fulfill the curvature requirement for optimal acoustic coupling between adjacent sources until
16 kHz. This is achieved with the minimum possible length for low distortion, but without being excessively short, which would
cause strong high frequency interferences. The 3” diameter voice coil and diaphragm construction allows a low cross-over
frequency. This makes this solution adequate for use with 5”, 6.5”, 8” and 10” speaker sizes, facilitating the high frequency
requirements of the Line Array mid band speakers.
