The SoundTube HP1290i is a 12-inch coaxial, two-way, high-SPL hanging speaker with an optional surface-mount configuration. Featuring patented BroadBeamHP® waveguide technology, the HP1290i delivers a consistent, wide-dispersion audio pattern (2–10 kHz, independently verified) for maximum intelligibility and coverage in high-output sound reinforcement, PA, and distributed audio applications.

The HP1290i integrates a 12-inch treated fiber cone with a coaxially-mounted 1.375-inch (35 mm) Mylar compression driver, delivering extended frequency response (59 Hz – 22 kHz, ±10 dB) and high efficiency (96 dB 1 W/1 M). Its injection-molded, glass-filled ABS enclosure ensures rigidity and durability for long-lasting performance.
