It has been a while since I have posted to the forum. I have an unused pair of Lowther DX3 drive units and have been wondering if they could be used in your midhorn as two-way system with 7Pi-18 (JBL 2241).

It's a pretty simple horn, probably best to build one and see. The things to watch are upper and lower crossover points, in addition to the overall response curve.
