2/3-BOLT TO 1-3/8"-18 TPI HORN ADAPTOR

Most modern professional audio speaker cabinets use low-cost, screw-on 1" compression drivers, while many high performance 1" compression drivers use two or three-bolt mounting patterns. The Eminence B2S-A solves this dilemma, allowing you to use the best compression drivers available, by turning two and three-bolt 1" horn drivers into 1-3/8"-18 TPI screw-on horn drivers. The cast aluminum design provides a stout, solid connection to both the driver and the horn. Bolt holes are drilled for 1/4"-20 bolts using the standard 3" spacing for 2-bolt drivers, and M6 bolts using the standard 2-1/4", 120° spacing for 3-bolt drivers. The 1-3/8"-18 TPI outer threads fit nearly all standard screw-on type horns and adapt the 1" exit of a bolt-on compression driver to the 0.94" throat of the horn. Mounting hardware not included. Made in the USA!
