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.
