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