Yamamoto Sound Craft AD1320 Throat Conversion Adapter for Onken, one pair

The AD1320 converts Onken's 455 and 500 series throats to 50mm diameter. One side of the adapter is threaded to fit an Onken driver. After conversion, it becomes the standard 2-inch throat size for professional use. It can be connected to Yamamoto Sound Craft's SS-300 horn, F280A, etc. It is cut from a round aluminum rod and plated with black anodized aluminum for durability. When connected to old driver units or the latest designs of horns with superior performance and sound quality, such as wood horns, you may find excellent musicality that could not be demonstrated with the original horns.
