Data Sheet

LF Pressed Chassis / Ferrite
TF1020
Features
10" bass and mid-range driver provides 97dB sensitivity and 150Wrms (AES
standard) power handling
2" High temperature copper voice coil wound on polyimide for increased
reliability
Ideally suited to compact enclosures and high pass systems
Rigid chasis design for maximum energy transfer
Kevlar-loaded cone with sealed surround and damping for reduced distortion
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. Measured on axis at 1W, 1m in 2 anechoic environment.
3. Xmax derived from: (voice coil winding width-gap depth)/2.
