I can't buy what I want 
. A full range 15" plus horn box that runs at 300W with 4ohm. Everything I see is 8ohm. I'll use an Eminence 15 Delta. I don't know what horn.
Question is......... I cant find a cross over for 4ohms. Where can I find one or a design to build?
What would the best frequency be if the bass driver runs from 40Hz - 4KHz?
