- Details
- Additional Information
Features Include
- 18" ferrite woofer provides 1000Wrms power handling (AES Standard) and 97dB sensitivity
- 4" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
- FlexirolTM surround for greater excursion control
- Double suspension for exceptional linearity at the highest excursions
- Low frequency response, down to 30Hz
- Smart chassis design minimises acoustic distortion
- Specially treated, weather-resistant cone
