Reviving this. I think I am set on the compression driver for the tweeter. But I am now considering going 3 way to reduce compromise on the almighty midrange. I would love something that can cover like 500-5k or thereabouts up top. I already have some high Qts 12" drivers I want to use for bass so that limits how high I can low pass the mid. I am kind of feeling the HiVi DMB-A. I will need to make the first XO point higher than 500 but it's still well below beaming for that 12". What do yall think? Any more obvious choices for a mid I'm overlooking?
