The AD1320 converts Onken 455 and 500 series throats to 50mm diameter. One side of the adapter is threaded to fit the Onken driver. After conversion, the size of the throat will be the standard 2" throat size for professional use. It can also be connected to our SS-300 horn, F280A, etc. It is machined from aluminum round bar and plated with black anodized aluminum for durability. If you connect it to an old driver unit or a modern horn with excellent performance and sound quality, you may find excellent musicianship that the original horn could not show.
