so I have this project, a pair of custom speakers utilizing 2235H woofers, Altec 811B horns and Radian 475PB compression drivers. Cabinets all drawn up and ready to be handed off to a cabinet maker. But then I thought, "if I'm going to all this trouble, wouldn't it be so much better if I had a midrange driver to handle, say, the 300-1,200 Hz range?" After some reading, it seems like the 2012H 10" midrange would be perfect for the role. Only problem - I can't find any. The question is, if I can find a shop with a couple 2012H recone kits, can these be used on 2123H frames?
