Key Features
• High-SPL, high-efficiency system for the
sound reinforcement and PA markets.
• BroadBeamHP
®
wide dispersion pattern
provides smooth off-axis coverage and
reduces overall system costs.
• One 203 mm (8.0 in) concentric coaxial
coated fiber driver, 25 mm (1.0 in) com-
pression driver with a 50 mm (2.0 in)
titanium diaphragm.
• Voice coil/8 Ohm direct & 70.7/100 Volt
model options.
• Includes tile bridge, safety cable
and backcan for ease of ordering
and installation.
• Low-profile design for clean appearance.
• Dual-concentric driver design provides
uniform horizontal coverage.
• Black & white color options.
Applications
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.
Ba
ckcan
HPCF8 in-ceiling speakers are packaged
with grille, tile bridges and backcan. HPCF8
backcan is UL listed for plenum spaces and
houses the electrical sub-assembly and all
connection hardware.
Crosso
ver Network
An advanced crossover network with
low-phase shift and impedance equaliza-
tion generates a coherent wave front. The
HPCF8 crossover incorporates UL-listed,
military grade glass-epoxy board material
for long-term reliability.
