PR 6x10

Engineering concept

A passive radiator allows for precise tuning of the low-end response without occupying internal enclosure volume, yielding highly articulate bass reproduction. The PR 6x10 passive radiator is a transducer engineered to transcend the limitations of conventional passive radiator designs. - The basketless, full-flat profile does not sacrifice internal enclosure volume for a given external dimension, granting maximum flexibility in acoustic volume design. - Its geometry yields twice the radiating area of a standard cone radiator of the same diameter, while minimizing the overall footprint. - The heavy use of aluminum in the membrane construction ensures structural stability even at peak sound pressure levels (SPL). - An included kit of adhesive masses allows designers to adjust the tuning frequency of the acoustic system by increasing the moving mass of the passive radiator to achieve the desired response.

Characteristics

The core focus of the development of the PR 6×10 is the suspension system—the most critical component in this type of transducer. The suspension must accommodate high excursion while maintaining excellent linearity and perfectly controlled mechanical damping. Extensive Finite Element Method (FEM) simulations enabled the optimization of the cone/surround/edges assembly to fulfill the initial design parameters, maximizing low-frequency extension while preserving the purity and accuracy of the audio signal.
