The  C158-8-085  is a  5.5 inch bass - midrange driver with ultra hard ceramic dome. A FEA optimized  overhung motor design with 25 mm titanium voice coil former guarantees extraordinary low energy storage and good heat transfer. The low loss rubber surround and a  thin fabric spider  center the moving parts with high linearity. As a typical small home stereo  bass - midrange driver, we recommend our C158-8-085 for an application from
38 Hz  - 3000 Hz.
