The HP129i is a 12” coaxial 2-way
hanging speaker with a surface-mount
option and a proprietary BroadBeamHP®
waveguide. Engineered to deliver true
high-SPL performance, the HP129i
incorporates a 12” treated fiber cone
and one 35 mm (1.38 in) Mylar compres-
sion driver with a professional-grade
electro-acoustic subassembly. The result
is a pendent-mount speaker with maxi-
mum efficiency (97 dB 1W/1M) and an
extended frequency response from 60 Hz
– 22 kHz (-10 dB). For lasting and rigid
performance, the enclosure is made from
injection-molded, glass-filled ABS.
