The newly redesigned Blue1 and Red1
have had their coil design reconfigured, and the effective moving mass
of their generating system has been reduced by 17%. The Blue1 and Red1
models use a four piece OTL cantilever technology, standard oxygen free
wire in the coils and Grado's specially designed elliptical diamond
mounted on a brass bushing. The Red1 model is selected from the Blue1
production run and meets higher test specifications. Approximately 10%
of the production run will meet these standards and become Red1 models.
