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 driver employs a phase plug for low compression and frequency
response shaping without the use of a dust cap.  The cast aluminium basket offers
str
structural rigidity heat sinking capacity for the motor and additional air ventinguctural 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.
