Product Details

Celestion TF1220 12" Professional Speaker 150W

Celestion's TF1220 12" PA woofer/midrange employs a 2" voice coil and 42 oz. ceramic ferrite magnet to achieve its conservative 150 watts RMS power rating. The driver's optimized cone and double half-roll edge do their part to ensure smooth, usefully extended response, and the rigid, non-resonant stamped steel frame protects the speaker's internal components. The TF1220's efficiency and versatility make it ideal for compact, good-sounding 2-way speaker systems.
