What crossove frquency should I use? I would like this to be as low as possible. Many thanks

Can I use these twitters on DJ speakers

As long as there is a dividing network in the speaker box. Yes you can use it

do you have an Australian agent as the delivery cost from USA is prohibitive?

No, however, you can check on Amazon for the same unit.

That kind of amp can I hook to these ?
