The AD1020 is an adapter that converts Altec and JBL 1" throat driver units to 50mm diameter. After conversion, it becomes the size of a 2" throat, which is the standard for professional use. It can also be connected to the SS-300 horn and F280A of Yamamoto Sound Craft. It is made of cast aluminum with black anodized plating for superior 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.

Adaptation	Altec and JBL 1" throat
Dimensions	118mm diameter, 100mm length
