Celestion TF-0818MR

Celestion TF-0818MR - Top curve: frequency response on axis | Secondary curve: frequency response at 45° off axis.

Nominal power: Tested for two hours using a continuous pink noise signal, bandwidth limited, according to AES standard. Power calculated at minimum impedance. Speaker tested in open air.

The continuous nominal power is defined as 3 dB higher than the AES rating.

Sensitivity measured on axis at 1W, 1m in anechoic environment 2Π.

Xmax is derived from: (voice coil width - gap depth)/2.

Small signal parameters are measured after the unit is subjected to a conditioning signal.
