Pioneer TS-D Series Speakers with Cones Made of Basalt

15 January 2008

Pioneer Electronics HAS launched its next generation TS-D series speakers which boasts a newly developed speaker cone made with basalt to increase its stiffness and strength.

A total of thirteen speakers in both the Pioneer and Pioneer Premier brands incorporate the newly developed Dual Layer IMX Aramid/Basalt fibre composite cone to deliver accurately detailed sound reproduction.

“Our speaker engineers are extremely passionate in their quest to build speakers that reproduce the highest sound quality possible. They are constantly looking at different materials that can be used to make a more efficient speaker with a stronger more rigid cone,” said Larry Rougas, vice president of marketing and product planning for the mobile business group of Pioneer Electronics (USA) Inc. “The basalt rock achieves this goal without adding weight to the cone, resulting in an open and smooth frequency response.”

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, aramid fibres and ceramic 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.
