Since the vertical coverage angle of sectoral and multicellular horns increases as frequency decreases and a second horn is usually added to cover the front rows for the higher frequencies in long-throw houses, a hump is often created in the response between 600-Hz and 3-kHz in the front area. A method is discussed of reducing the hump in the front -house- curve, making the transition from the front row to the rear row smoother, with a controlled decrease in high-frequency response similar to that due to air absorption.
