If the local cannot get it, then yeah for sure on to scottHi Terry J, Very nice speakers you have there mate, what Model/Brand are they ?? I love my 2 channel as well but more into HT now...
As far as the speaker grill cloth, Scott from spotlight Geelong will ship it to you no prob's, $10au to ship AU wide I think...
Hope to see more pictures & idea's of what you end up coming up with mate...
diy speakers, bit of a write up here
actually, you may be able to help.
there is a dutch site that had a project very heavily into diffusion, heaps of pics. used tons of mdf to do the build.
this looks very much like it could be it, but randomly pressing buttons I have not come across the thing I am thinking of
have you any idea of what it is I am looking for from my vague description??
