Woofer 12", 450W AES, 900W Program |  |
|
|
|
Very good power handling, excellent linearity and very low distortion.
Copper voice coil construction, suspensions and cone materials designed to survive at 450 Watt RMS power.
Applications
The excellent linear response, well controlled down to 50 Hertz, makes the LF12G301 especially suitable for band-pass subwoofers and small size bass reflex systems. It is a very good solution for two or three way system when a good BL and punch is required. |
