ZERO OHM COIL

AIR CORED COILS
COILS
Air cored coils are, for physical reasons, unbeatable as far as accurate pulse reproduction
and freedom from distortion are concerned. For this reason, for all the purists, we stock air
cored coils with wire diameters of up to 3.0 mm. It is also possible in this way to create
greater inductances with relatively low internal resistance. Vacuum impregnation, which is
described in detail at the end of the chapter "Zero Ohm Coils", also leads in the air cored coils
described here to greater detail and spatial quality in the reproduction of music.
