Features
- 15" neodymium woofer offers 450Wrms (AES standard) power handling and 98dB sensitivity
- 3" edgewound voice coil for higher efficiency and excellent distortion control
- "M-Roll" surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range
- Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio
- Intelligent heat management in both chassis and magnet assembly design further minimizes distortion
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.
- Small signal parameters measured after unit subjected to pre-conditioning signal.
