I finally finished both speakers. It worked out great even though the Kilomax drivers aren't oriented up and down but what I've done is tilt one left the other right so they look like they were meant to be channel specific. I put the Pi symbol on a different side of each speaker to enhance the illusion. I've just spent the last hour listening to my Song Remains the Same Led Zep DVD in 2 channel(btw highly recommended DVD-they really captured the whole 70's concert scene - gotta love John Bonham speeding out on drums -and Jimmy with his Dazed and Confused solo with the violin bow). They sound wonderful, I'm happy to be back to horn based speakers. And the good news is the day I finish these - my Taylo Ref II's sold, gotta love that timing! Bill E. - do you recognize these speakers?

Now onto the centre channel.
