FIR crossover filtering for transparent midrange. Plenty of sound-shaping options with four EQ presets—Bass Boost, Flat (LF), Flat (MHF) and Contour. Very low total harmonic distortion, so no listening fatigue. System"s sound is easy to control and shape, even from the stage. On-target, directional PA aiming to reduce reflections off walls and ceilings.
