Features
- 18" ferrite magnet, cast aluminium chassis LF driver delivering 700Wrms (AES Standard) power handling and 94dB sensitivity
- 3" high temperature, multi- layer voice coil for greater motor force
- FEA optimized magnet assembly delivers highly symmetrical cone - movement, leading to exceptionally low harmonic distortion
- Balanced Airflow Venting (BAV) on the front-plate increases airflow to provide enhanced cooling
- Dual Magnet Motor (DMM) incorporates a secondary magnet used to increase overal motor force (Bl) without the need for any additional increase in magnet size
- "Multi-roll" surround provides exceptional linearity at extremes of cone excursion
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.
