RCF L12L750, Mid-Bass 12", 350 Watt RMS / 8 Ohm

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.

Features 4-inch, fiberglass former, edgewound aluminum voice coil 700W continuous program power handling 101 dB Sensitivity 60 Hz - 2 kHz Frequency range Shaped Shallow Triple-roll damped surround Inverted dust cap
