That's a nice informative long post. AND what I told you last night gearstix!! Don't cheat yourself or your woofers by doing it 1/2 ass. There are many skilled Nov builders on here that can design you something fierce. Get some designs, get some quotes, but wood, build, and get loud!! Keep in mind you might gave to do the blow thru after building a large shallow wall or small wedge if your not happy. Do you have an amp yet??
