Here you get a brand new GRS phenolic ring tweeter rated at 8 ohms and 30 watts. This will be to replace your blown CTS made phenolic ring tweeter as found in 1970's early 1980's era bookshelf speaker cabinets such as Kenwood, Marantz and Pioneer. The full outside diameter is 4 and 3/16". The cone which I think is paper is about 1 and 3/4" in diameter. Item will be properly packaged and shipped promptly ~ see my feedback ~ and take a close look at the lovely photos. Thank you.               This listing is AI free
