I would use a set of components and just replace both the woofer and tweeter at the same time. If you go this route, don't select a 2 or 3 way speaker and a separate tweeter, get a matched component set. I would also cut off the woofer so that when you turn it up loud the woofer does not distort because of the bass. When you have your stuff, post or PM me and I will tell you how to do that.
