"GIP" GRAPHITE INJECTED PLASTIC
CONES With conventional
speaker cones, they have multiple design problems:
Non-uniform cone thickness (heavy and
often generate internal "bending" motions which generate distorted
sound)
Self-resonant materials and construction
(standing waves occur creating strong tonal shifts)
Paper and cheap poly cones warp and
change mass over time due to swings in temperature and humidity thus degrading
performance
