I don't know why the US is so blessed with high-excursion- maybe for all the road-going boom-boxes?

Since the Mach5 drivers are sourced out of China, it shouldn't be too hard to convince them to make a stop in Aussieland at some point? The ones we make locally however, are cheap, especially since the dollar has fallen so much. Shipping is what kills it, I'm guessing.

As far as IB, don't bother unless you have high excursion drivers, or a lot (like 8) medium excursion ones. Box subs- when properly designed- are fantastic for the amount of sound they can put out. And you can build them like a HT- build the box in the ceiling if need be.
