Features
- 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
8Ω Frequency Response
- Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.
- Measured on axis at 1W, 1m in 2π anechoic environment.
- Xmax derived from: (voice coil winding width-gap depth)/2.
