What I like about this piece is the fact that the guy
built them as a joke out of scraps and it's become his
main system. Good graphics too.

What puzzled me was the use of the Audax driver (purchased
in UK) which I have not heard much about. Elsewhere it said
that PE had 'em but a quick check of the catalog came up empty.

Other variation on this that intrigues me is the voigt pipe
that uses one speak facing front and another facing back...
forgot the term for it. :-P
