RCF L12L750 12" MID-BASS LOUDSPEAKER

Very high efficiency and extended linearity are special features of this mid-bass transducer.

Very efficient heat dissipation is ensured by a radiator that is part of the basket design.
The aluminum voice coil offer a properly aligned Q factor and a very high sensitivity.
A specially designed Shallow Triple-roll surround guarantee a very low midrange distortion.
Fiberglass former voice coil, polycotton suspensions and treated cone provide the very high power handling.

Applications
  • • The L12L750 is primary designed to be horn loaded in medium and long throw systems.
  • • The dust cap is inverted in order to minimize the cone distortion and for better coupling to a phase plug.
  • • When mounted in compact size bass reflex enclosures, the good combination of short voice coil, very low mass and suspensions control makes the L12l750 a very good choise for high power, 2 way, satellite applications.
