Medium-Throw Downfill HF Loudspeaker
The KF913F is a dedicated medium-throw HF downfill module engineered for use with Phase Point Source Technology digital signal processing in the creation of PPST arrays. It provides coverage from -0 degrees to -45 degrees below the horizontal axis with flat frequency response, with usable response down to -60 degrees. In stadium and arena applications where the highest seats are above the array, an inverted KF913F can provide “up-fill” coverage. Because the enclosure’s bottom is sealed, the downfill element can be placed at any location in the array. Maximum throw is 400 feet.
