Peerless Gold
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
spider so as to again reduce air compression effects. The cone in this model is
damped black polypropylene, offering a unique visual and acoustic experience.
