Pioneer speakers have been outputting headache-inducing rock for decades. But the company has just announced its TS-D line of speakers with cones made of basalt fabric. The company says the volcanic stone is pulverized and melted at 2700 degrees before being drawn into fibers. The resulting fabric increases the speaker cone's rigidity and strength while keeping weight low.
In a press release, Larry Rougas, Pioneer mobile business group's VP of marketing, said, "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. The basalt rock achieves this goal without adding weight to the cone, resulting in an open and smooth frequency response."

Their are 13 speakers in the TS-D lineup, will be on sale soon at prices starting at $150.
