- Compact, high flux, dual magnet motor design
- Vented cast aluminium heatsink
Topmost curve: Frequency response on axis | Secondary curve: Frequency response at 45° off axis
Power rating: 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.
Continuous power rating: Defined as 3dB greater than the AES rating.
Sensitivity: Measured on axis at 1W, 1m in 2π anechoic environment.
Parameters: Measured after unit subjected to pre-conditioning signal.
Xmax: Hvc-Hg/2
