Hifi woofers

Mundorf's BS series uses a solid 99.99% OFC copper round conductor stabilized by varnish, wrapped around a rod-shaped iron-silicon alloy core. Each end of the stick is fitted with a hole for attachment.

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.

This 5.25 inch 8 ohm member of the NE family has leading-edge transducer technology packaged in a cutting edge, stylistic design. The woofers in this family feature an innovative cast aluminium basket design which minimizes acoustic reflections inside the driver, through large basket windows and sculpted basket spokes. The basket also is designed to act as a highly coupled heat sink to the Neodymium-Iron-Boron magnet (NdFeB) motor, so as to improve power handling capacity. The cone and dust cap are constructed of natural wood fiber material with proprietary coating formulas and processes, so as to yield high clarity products. The cone designs also utilize pentacone technology for improved frequency response. The voice coil bobbin is titanium, for improved performance. The FEA-designed motor features copper caps to minimize inductance and extend performance to high frequencies. Rounding out the design is a 4-way terminal block connector, for ease of electrical connection.

This 15 inch 4ohm member of the SDF product family has all the design features suitable for a high performance, high excursion subwoofer. The motor features a strong ferrite magnet with bump T yoke, supporting high excursion, and aluminium shorting rings and pole extenders, lowering and linearizing the inductance of the overhung voice coil. The paper cone is vented under the dust cap, to reduce air compression. The suspension system features a low-creep rubber surround, and a optimized spider, ensuring long-term reliability under high power conditions. The product also features a upgraded die cast basket.

This 15 inch 8 ohm speaker features a FEA optimized ferrite magnet motor, a 2 inch high-temperature voice coil, and a high strength stamped steel frame.
