RCF L12L750 8/ohm

Reproduktor RCF 12", 350W, 101dB, 60-2000Hz, X-max 3,5mm, hmotnost 11,5kg

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.
