INTRODUCTION
The Transducers
The PSR-8i passive speaker
features a 8-inch high-power
low-frequency woofer and a
1.5-inch aluminum diaphragm
high output precision
compression driver. This
high-frequency driver is mounted
on an acoustically nonresonant
exponential waveguide, providing
a wide, controlled dispersion
and precise reproduction of the
critical upper mid-range and high
frequencies. The result is an
unbelievably smooth off axis
response that allows everyone
in the audience to experience
the same high-resolution audio
no matter where they are seated.
Each driver has been specifically
desiged by our engineers for
optimum performance in the
lightweight high-strength cabinet.
Passive Speaker System
Thank you for choosing
Passive sound reinforcement speakers.
The PSR-8i is an passive
two-way loudspeaker capable of
extremely high sound pressure
levels, and designed to give you
the best performance of any
loudspeaker in its class and price
range.
Our design goal was to build a
sound reinforcement speaker with:
1.High precision, high output, and
accurate reproduction.
2.Very wide, smooth dispersion of
mid and high frequencies.
3.Ergonomically design for easy
transport and set up.
Through the combined resources
of our mechanical and analog
engineers, we were able to achieve
our design goals in every respect.
The result is a sound reinforcement
system equally at home in a concert
setting, studio, cinema, or in a home
theatre.

The Cabinet
The PSR-8i cabinet was designed to be the strongest moulded composite
cabinet on the planet. This material is rigid enough to prevent unwanted
vibrations in the cabinet. It has built-in flying points for hanging, and a
socket in the bottom for mounting on a tripod stand. Although it is an
exceptional choice for portable sound system use. The asymmetrical
trapezoidal design f the cabinet makes it easy to use as a floor wedge
for stage monitor applications.
