The speaker cone in the new TS-D speaker range is made out of basalt because according to the
Pioneer engineers, it's ‘rigid, heat resistant and delivers more detailed and accurate sound.'
Pioneer's innovative speaker technology takes basalt fibres interwoven with Aramid fibre. The Dual Layer IMX Aramid / Basalt fibre composite cones are designed to deliver accurately detailed sound reproduction.
Pioneer's Product Manager for the mobile electronics group, Breanna Hanke said, "Pioneer speaker engineers are constantly looking at different materials that can reproduce the highest sound quality possible. Basalt was chosen for its strength, heat resistance and rigidity. The result is a cleaner bigger sound."
The new cones consist of a high-tech sandwich of basalt and ceramic components. The basalt, before it is turned into a fabric, is pulverized and melted at more than 2700 degrees Fahrenheit and then drawn into fibres. The combined materials of basalt fibres and aramid fibres are used to reinforce Pioneer's composite injection moulded polypropylene (IMPP), creating an extremely strong speaker cone that can withstand flexing associated with excessive cone movement and produce an improved transient response in the mid to low frequency spectrum.
