Caratteristiche
- 21" neodymium subwoofer offers 1600Wrms (AES standard) power handling and 98dB sensitivity
- 5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
- Double suspension and a "multi-roll" surround provide exceptional linearity at extremes of cone excursion
- Rigid lightweight carbon fibre loaded cone delivers improved performance and faster response
- Intelligent heat management in both chassis and magnet assembly design further minimizes distortion

Note
(1)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.
(2)Measured on axis at 1W, 1m in 2pi anechoic environment.
(3)Xmax derived from: (voice coil winding width-gap depth)/2.
(4)Small signal parameters measured after unit subjected to pre-conditioning signal.
