The diaphragm are precision completely formed from pure titanium. Voice coil assembly is designed using high temperature kapton former and it is joined to the diaphragm by RCF proprietary Direct Drive kapton technology. Diaphragm suspension is designed by extensive FEM study for low distortion and low frequency range
extension.


Applications:

Perfect driver for professional high performance applications, from high power 2-way systems to multiple-way long throw systems and medium to large format line arrays.
Very compact size and easy to crossover, offer the clarity of the 1" and the efficiency and power handling of a large format compression driver.
Very good linearity and efficiency in combination with RCF HF series horns.
