RCF L15P530 - 15" 350W 8 Ohm part for Martin Audio LE400 DLS531

High power 15" mid-bass.

Very high sensitivity, 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:

A very light maving mass, a curve response linear above 3 kHz makes the L15P530 a very good solution for high quality two or three way system.
The aluminum voice coil guarantee a very high efficiency in conjunction to a proper Q factor for a good bass response.
