The HP129a is a 12", coaxial, hanging speaker with a surface-mount option and a proprietary BroadBeamHP® waveguide. Engineered to deliver true high SPL performance, the HP129a incorporates a 12" treated fiber cone and one 35 mm (1.38") Mylar compression driver with a professional-grade electroacoustic sub-assembly. The result is a pendant-mount speaker with maximum efficiency (97 dB 1 W / 1 M) and an extended frequency response from 73 Hz - 19 kHz (±10 dB). For lasting performance, the enclosure is made from injection-molded, glass-filled ABS.

Mounting hardware is included and features hanging and safety cables, Euroblock connector and terminal weather boot. For easy ordering, stocking and installation, every speaker is equipped with a five-position tap switch for 25, 70.7, and 100 V applications with a transformer bypass setting. For surface-mount applications, SoundTube offers a surface-mount adapter (AC-HP-SM129).
