DUB DISCUSSION BOARD

I'm thinking about making some speakers which can play dub on an outside-party.
Is there a dub-speaker-making-tutorial out there somewhere?

We have an old discussion about this on the board:

Most of the mentioned links still work altough the discussion is seven (SEVEN!) years old:

I hope this helps..
