Dual-Layer IMX™ (Injection Molded Matrix) Aramid/Basalt Fiber Composite Cone
TS-D1720C
To create speaker cone material that performs well at natural sound reproduction,
Pioneer engineers take Basalt fibers interwoven with Aramid fibers and combine it
with foamed IMPP to create new-generation IMX cones which are light, rigid and
moderate inner loss. The process of turning Basalt rock into Basalt fiber consists of
pulverizing this natural volcanic rock that is most commonly found on Earth’s crust, melting it at over 2,700° F. and drawing it into long hairbreadth-thin fibers. The foamed
IMPP hardens and fuses to the Basalt fibers, creating a one-piece cone. The result:
TS-D speakers reproduce natural, detailed sound, are stable in temperature extremes
and are eco-friendly.
