Overview

Eminence S2B-A Aluminum 1-3/8"-18 TPI Screw-On to 2/3-Bolt Horn Adapter

Many modern professional audio horns and waveguides feature only two and three bolt mounting patterns for compression drivers. The Eminence S2B-A solves the dilemma of using 1", 1-3/8"-18 TPI screw-on horn drivers with those horns and waveguides.

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 2-bolt pattern, and M6 bolts using the standard 2-1/4", 120° spacing for the 3-bolt pattern. The 1-3/8"-18 TPI inner threads fit nearly all standard screw-on type compression drivers. Mounting hardware not included. Made in the USA!
