The Grado Black1 and Green1 cartridges are upgraded versions of the originals. The effective mass of their generating system has been reduced by 17% and their coil design revised. These improvements provide improved tracking, transient speed and resolution. Out of the Black1 production run, 15% of the units that meet the highest test specifications are chosen to become Green1.
The Black1 and Green1 models use a three piece OTL cantilever technology.
