Description:
The new Peerless HDS product line continues the tradition of Peerless' High
Definition Sound (HDS) products. 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 aluminium, offering a unique visual and acoustic
