China Cones improve the accuracy of audio systems by reducing resonance. This electronic and mechanical resonance causes subtle phasing errors which reduce fidelity. China Cones are made from a high density ceramic material that does not resonate within the human hearing range, and so vibrational energy is brought under control without audible colouration. China Cones have been specifically designed to acoustically decouple your speakers and audio equipment from shelves and stands, eliminating unwanted but audible resonances that colour the source material: the special cone shape will restore and maintain the integrity of all complex audio signals.
