Overview

Peerless by Tymphany SDF-250F75PR01-06 10" Paper Cone Subwoofer

The 10" 6 ohm SDF-250F75PR01-06 from Peerless by Tymphany has all the design features you can expect from a high performance, high excursion subwoofer. The motor features a strong ferrite magnet with bumped T yoke to support high excursion. In addition, to increase damping and cone control, the motor includes aluminum shorting rings and pole extenders, all of which lowers and linearizes the inductance of the overhung voice coil. The venting under the paper cone and dust cap reduces air compression for more predictable high output performance. The suspension system features a low-creep rubber surround and an optimized spider, ensuring long-term reliability under high power conditions. This subwoofer also features a newly designed, ultra rigid, cast aluminum basket.
