Hey just got a pr of kove Armageddon 4in coaxials. Says thier a dual concentric design. Looks kinda like a dome mid with a dome tweeter sunk in the middle. Has anyone used these before? Wanting to use in my kick panels. Thier missing the owners manual. Does anybody know what kind of crossover points thier good at? Found in the back room of a local store. Don't seem to have ever been used. Hooked them up to my home receiver. They sound pretty good/get loud. Something new to play with and only cost $15 bucks
