Peerless 5 1/4″ 830991 Woofers, PAIR

Light testing use. Functionally perfect. Some minor cosmetic blemishes (see photo at 100%).

From Peerless/Tymphany:

  • Truncated cast aluminum frame
  • Glass-Fibre Composite (GFC) cone with half-roll rubber surround
  • Long-throw voice coil
  • Shorting rings for reduced distortion
  • Under-spider and voice coil ventilation

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. The Glass-Fibre Composite (GFC) cone offers a unique acoustic and visual experience.
