Inverted dustcap for close positioning of phase plug
High temperature, environmentally robust foam surround
Copper sleeved pole reduces HF inductive rise
Chassis design allows for fixing of rear cover
8 Ω Frequency Response
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. Continuous Power Rating is defined as 3dB greater than the AES rating
3. Measured on axis at 1W, 1m in 2Î anechoic environment.
4. Xmax derived from: (voice coil winding width-gap depth)/2.
5. Small signal parameters measured after unit subjected to pre-conditioning signal
