Field Coil Driver
DRIVER S20
The heaviest field coil driver ever made on earth, S20 serves as our sub-woofer horn driver.
It has an incredibly large field coil and an outstanding magnetic circuit that brings
unprecedented power and efficiency; a specially made sandwich titanium
diaphragm can withstand huge pressure without deformation.
Only 1-watt energy in the voice coil is all you need to shake the earth.
