  coated fiber driver, 25 mm (1.0 in)
  compression driver with a 50 mm (2.0 in)
titanium

diaphragm.

• Weatherized components and sealed
input panel for indoor/outdoor
applications.

• Switchable dual input option for either
voice coil/8 Ohm direct or 70.7/100
Volt

applications.

• Multiple installation hardware
options for overhead and surface-
mount

applications.

• Integrated hanging and safety cables
for easier and cleaner-looking installs.

• Fine black or white paint finish.

Applications

The SoundTube HP8i is a premium 2-
way low-profile, high-efficiency, high-SPL
speaker with BroadBeamHP

technology

providing a wide dispersion pattern for the
sound reinforcement and PA markets.

The HP8i is engineered for installations
requiring full-range background/fore-
ground music plus paging. A smooth and
even coverage pattern makes the HP8i
an ideal choice for use in warehouses,
gyms, aerobic rooms, super stores, theme
parks and other open-ceiling or outdoor
applications where high SPL is required.

Cast Composite Enclosure

SoundTube’s HP8i cast composite enclo-
sure provides a low-resonance platform
with effective self-damping properties for
a clean, tight sound. Compression cast
glass-fiber composite material coupled with
SoundTube’s patented ZeroReflection

™

internal shaping provides extreme stiffness,
eliminating internal standing waves and
external diffraction distortions. The result
is accurate sound and tight bass in a com-
mercial speaker.
