Overview

Peerless by Tymphany 830874 6-1/2" PPB Cone HDS Woofer

The Peerless High Definition Sound (HDS) Series offers high-quality solutions for multi-way speaker systems employing vented box alignments. A powerful ferrite magnet system is coupled to a finite element analysis-designed suspension system, containing a linear spider design and rubber surround. The motor incorporates an aluminum shorting ring that reduces coil inductance, extending frequency response performance and reducing second harmonic distortion. A cast aluminum basket provides high structural rigidity, heat-sinking capacity for the motor, and additional ventilation under the spider that in combination with a vented cone neck reduces air compression effects. Peerless developed the proprietary and highly advanced Polypropylene Black (PPB) cone material used in the HDS PPB Series, creating a stiff but still dampened cone that remains stable even under the greatest sound pressures.
