The HPCF8 is a high-SPL flush-mount
speaker with BroadBeamHP® dispersion
technology providing a wide coverage pat-
tern for in-ceiling applications. The HPCF8
is engineered for installations requiring
full-range background and foreground
music plus paging. A smooth and even
coverage pattern makes the HPCF8 an
ideal choice for use in gyms, aerobic rooms,
convention centers, stadiums and other
high-power in-ceiling applications.
