L12P540
WOOFER
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 system.
- • It is a very good solution for two or three way system when a very high BL and good punch is required.
