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.
