What is this shorting sleeve?
Copper Shorting Sleeve
The shorting sleeve is a conductive copper sleeve placed in the air gap between the pole piece and the voice coil former to
reduce inductance. Inductance can best be understood as the change in magnetic energy that occurs as the voice coil moves
in and out of the air gap. In most drivers this energy is absorbed by the voice coil, causing impedance rise, introducing
distortion and reducing the woofer’s ability to play at the top of the midbass spectrum. In the X-Series midwoofer, the shorting
sleeve simply absorbs changes in inductance, optimizing the sound quality, output potential and frequency response of
the driver.
Perhaps the most distinguishing component of the X-Series midwoofer is the innovative copper shorting sleeve system. This
technology prevents a rise in inductance caused by the movement of the driver, which has several positive impacts on the
woofer’s performance:
• Improved power delivery to the voice coil
• Decreased inductive distortion
• Improved cone linearity
• Improved high-end extension
• Decreased risk of overheating
