Product Description
This 6.5 inch 8 ohm driver is a member of the high performance HDS family. A powerful ferrite magnet
system is coupled to a finite element analysis designed suspension system, containing both a linear
spider design and a rubber surround. The motor contains an aluminium shorting ring, which reduces coil
inductance, thus providing both extended frequency response performance and reduced distortion. The
long-throw voice coil ensures linear high excursion performance, needed for signal clarity. The cone
necks are vented so as to reduce air compression effects under high excursion conditions. The cast
aluminium basket offers structural rigidity, heat sinking capacity for the motor, and additional air venting
under the spider so as to again reduce air compression effects. The cone in this model is nomex based,
offering a unique visual and acoustic experience.
