A Differential Dispersion horn has a 3D trapezoid dispersion pattern which distributes sound over a plane at the artist’s head-height more evenly than a system with a conventional, fixed-dispersion X° x Y° type horn, which produces an imperfect coverage pattern which misses out some areas — particularly either side off-axis close to the monitor.

LE Series monitors produce a well-defined coverage pattern at head-height with wide horizontal coverage when standing very close to the monitor. Further back, the dispersion progressively narrows, increasing the SPL to compensate for the increased distance from the monitor. The frequency response is unchanged, so the artist hears essentially the same sound balance and level wherever they stand within the coverage area. This consistency in frequency response and SPL — both close to the monitor and further back — is exceptional.
