Loudspeaker Kit components are shipped by WES. Also in Aus, Wavecor & Visaton drivers are stocked by Soundlabs,
DJ City have some Faital product, & good xover components are available from Speakerbug.
Frankly, I'd take the trouble to learn how to design a crossover (Look at Rod Elliott's Articles). It's not as hard as many here make it out to be (Usually those who over-complicate the process by using simulation software). You just need the right formulae, manufacturer's data, and a modicum of common sense.
