There is scarce availability of horns for 2" compression drivers without 18TPI screw on adapters.
I'm running my driver at very low SPL but would like to experiment with a wider range of horns. The airflow diameter will be restricted before opening up in this scenario.
I purchased ADM25-50, hoping to couple the horn with drivers, but this adapter is meant to be used the other way around.
Do you know where to find a 1 3/8 male-to-male threaded coupler?
Thanks in advance!

Use two adapters:
2" --> 1"
and
1" bolt on (driver side) --> 1" screw on (horn side)
or mount two of the latter back to back,
or chop off the threads of the horn and glue on a DIY adapter plate.

I found this:
Eminence B2S-A Aluminum 2/3-Bolt to 1-3/8"-18 TPI Screw-On H
Found this for threading my own pipe ...
Die 1 3/8-18 UNF Dies Threading 3/8-18 DIE Superior quality
