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
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.
