YG Acoustics BilletCore midrange and midbass drivers. The drivers were CNC-machined in-house from solid blocks of aircraft-grade aluminum, in a meticulous and precise process with tolerances under 20 microns (0.0008″).
Machining from solid allows YG Acoustics to incorporate reinforcing ribs into the cones, which would not be possible using traditional production methods.
In the photo above, finishing specialist Samson is inspecting the anodizing quality on each and every cone before approving it for assembly.
