Dual chassis - can speakers be biwired?

So, ideally, you should have a set of cables having 4mm banana plugs & a set of cables having spades. 

That's an interesting tip mixing bananas and spades at the amp end. Would allow different cables for bass and treble as well if you wanted to do so.

Indeed - And that's what I've done in my arrangement ... (chk my sig)

That's the problem with the tapatalk app, it hides the signature, now checked, thanks.

This is going to open up a world of extra options for me to think about.
