Applications 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 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.
