PRD500
Planar Ribbon Driver
The PRD500 is a high performance planar ribbon driver with
very high sensitivity/output capabilities developed for wide
range of professional and consumer applications were highest
quality accurate sound reproduction is required.
Unique Features:
Kapton diaphragm, massive cast face plates,
horns and back cup, gold plated terminals,
symmetrical push-pull Neodymium magnet system
Driving force directly acts on the diaphragm and is
evenly distributed over the radiating surface
providing freedom from break-up resonance,
transmission delay and losses
Flat diaphragm provides the ideal shape for sound radiation, that is frequency
independent, results in even and coherent wavefront, even dispersion, no wave
cancellation, no signal delays, no horn throat related colorations
Purely resistive impedance, virtually free from inductive component
Extremely light diaphragm compares by mass to associated vibrating air volume,
being extremely light it creates ideal condition for sound energy transfer, accurate
signal resolution, very high sensitivity and high frequency output extension
The PRD500 driver can be used with variety of faceplates and horns suited for specific
applications (picture shows PRD500 with 70 x40 horn). The PRD500 is specifically
suitable for true line source systems that provides appropriate coupling at high
frequencies resulting in coherent, free from distortion and colorations, long throw sound
energy beam. For more detailed information please download a white paper on PRD
