B&C DE7 compression driver adapter

This adapter allows the B&C DE7 0.75" compression driver to be mounted to a standard flanged 1" horn. The DE7 mounting holes are sized to accept 4mm heatset inserts for a more robust threaded connection for driver mounting. The horn mounting side has holes sized for 4mm bolts or screws. The adapter throat is about 1" long and has a linear taper from 0.75" to 1.0"
