Description
The HP890i is a premium 8.0” 2-
way, ported high-efficiency, high-SPL
loudspeaker for distributed or 8 Ohm
applications. The HP890i incorporates a
dedicated 8.0” treated fiber driver and
high-power compression transducer
with a BroadBeamHP® waveguide to
deliver a consistent dispersion pattern
and superb intelligibility for the fore-
ground music, sound reinforcement and
PA markets. The HP890i incorporates a
120 Watt transformer with a 5-position
tap switch and voice coil/8 Ohm direct
position. Hanging hardware is included
and features a fast-action SpeedClamp™
for easy and secure installation.
