he unique "MicroSphere" coating is one of the the main reasons for the unrivaled sonic precision of the new 165 mm / 6.5" high-end mid-woofer GRAPHIC GL6. In a patented process micro ceramic hollow spheres with a diameter of 75 micron are being embedded in a polymer layer and applied to the cone. The coating ensures perfect inner damping without any negative impact on the moving mass. This innovative technology rather increases the stability of the hand-scooped cone, allowing better dynamics and higher sonic definition than ever before.
