The Ivan stands for strength and power.
First we start with a high power, long excursion 10" driver.
The cone is made out of a paper and carbon fiber blend for increased strength. A patented magnet structure is used to create a very uniform magnetic field, which means the voice coil is always in an optimum magnetic level resulting in low sound distortion. To further reduce distortion, aluminum and copper shorting rings are used in the motor section to lower coil inductance. Power handling of the woofer is made possible by the 6 layer copper clad aluminum wire voice coil.
