Wayne sells any of the Eminence drivers you would need. Buy just the raw drivers and make up your own crossovers and wiring, Or buy the kits Wayne sells. The kits include a crossover, Termianals and wiring. Everything you need except a cabinet which you build yourself. Eminence makes very good drivers and none other compare for the price. Build a Pi design or just use the components. I would say if find Pi kits of Eminence drivers too costly you have bigger problems than shipping. Shipping is a killer. Cost 675 to ship a big pair of corner horns in a crate from coast to coast. That was almosty 20% of the speakers, and its costly.

Good luck, Have some fun.
