Preliminary Technical Information
Key Features
• High-SPL, high-efficiency system for
the sound reinforcement and PA markets.
• BroadBeamHP® coverage pattern pro-
viding smooth response and maximum
SPL across the audio spectrum.
• One 305 mm (12 in) treated fiber cone
with a treated cloth surround and one 35
mm (1.38 in) Mylar compression driver
with waveguide.
• Reduced amplification costs and maxi-
mum efficiency (97 dB sensitivity), with 8
Ohm impedance.
• Weatherized components indoor/out-
door applications and a ported enclosure
for added bass response (down to 60 Hz,
- 10 dB).
• Easy-access 5-position tap switch for
25/70.7/100 Volt and 8 Ohm settings
allows for easy ordering, stocking and
installation.
• Included accessories: hanging hard-
ware, Euroblock connector, terminal
weather boot.
• Optional accessories: surface-mount
bracket (AC-RS-SM129).
• High quality black or white painted
finish. Custom colors available.
Description
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.
Mounting hardware is included and
features hanging and safety cables, Euro-
block connector and terminal weather
boot. For easy ordering, stocking and
installation, every speaker is equipped
with a 5-position tap switch for 25, 70.7
& 100 Volt applications with voice coil/8
