BMW E30 Premium Rear Tweeter Hertz DT 24.3 Surface Mount Plate

These are included in the Hertz DSK 130.3 component speaker set. The center hole is 36mm which may fit other tweeters. Note the original BMW perforated cover/grill will not fit over these unless you cut the Hertz grill. See my countersunk version if you want to use the original perforated cover/grill.
