Yamamoto Acoustic Craft AD1420 Throat Conversion Adapter, 1 pair

The AD1420 converts a 35mm diameter throat to a 50mm diameter throat for Altec 288 series drivers. After conversion, it becomes the standard 2-inch throat size for professional use. It can be connected to Yamamoto Acoustic Craft's SS-300 horn, F280A, etc. It is machined from a round aluminum rod and plated with black anodized aluminum for superior durability. When connected to old driver units, wood horns, and other modern horns of superior performance and sound quality, you may find excellent musicality that could not be demonstrated with the original horns.
