Woofer 12", 400W AES, 800W Program |  |
|
|
High power 12” woofer. Very good power handling, excellent linearity and very low distortion. Very efficient heat dissipation is ensured by a radiator that is part of the basket design. The air is forced in the radiator thanks to a sealed spider design.
Applications
The excellent linear response, well controlled down to 50 Hertz, makes the L12P540 especially suitable for band-pass enclosures and small size bass reflex systems. It is a very good solution for two or three way system when a very high BL and good punch is required. |
