        Product details

        Peerless by Tymphany HDS-P830992 4" GFC Cone HDS Woofer

         

        This 4 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 a glass fibre composite, offering a unique visual and acoustic experience.

        Bought this for a portable boombox. It is a little heavy. But compared to those full range neodymium drivers (from dayton audio for example) this blows them out of the water. In terms of efficiency and distortion. Sound is way more clear. Driver is more expensive though. However it has a cast metal basket, not those stamped metal cheap stuff. Paired with a tweeter, these can do nicely in a variety of projects.
