Celestion LF Pressed Chassis Ferrite TF1530

* High output 15" bass and mid-range driver

* Efficient magnet assembly enables 99dB sensitivity and 400Wrms (AES standard) power handling

* 3" high temperature copper voice coil wound on polyimide for increased reliability

* Double roll surround for greater excursion control

* Superb price/performance ratio

8 Ohm 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 2p anechoic environment.

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