LF Pressed Chassis / Ferrite

TF1225

12" Bass and mid-range driver providing 97dB sensitivity and 250Wrms (AES

standard) power handling

2.5" high temperature copper voice coil wound on polyimide for increased

reliability

Optimised ferrite magnet design reduces weight

Double roll surround for greater excursion control

For use in 2-way or compact 3-way systems

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 Handling is dened as 3dB greater than the AES rating.

3.Tested as per the EIA-426-A standard.

4.Measured on axis at 1W, 1m in 2Î anechoic environment.

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

6.Small signal parameters measured after unit subjected to pre-conditioning signal.
