    Looking excellent, John! I'm anxious to hear them. I wish they could play the music a little louder at MWAF, however, so the audience could get a better audition. Perhaps you will be able to bring them to InDIYana 2020 for a more substantial audition.

    Thanks guys I hope they sound decent. They have not been out of my basement so that's makes me a bit nervous how they will sound in a bingo hall. With respect to originality, I copied everything as shown in posts 1 and 2. Hopefully the judges don't read PETT.

    Cool. 10 for originality? When I first looked at your pics, it almost seemed like the deflector was either floating in free air or mounted directly to the top of the tweeter. Have to bring my macro lens to snap a few closeups. .

    Looking good John! Knowing you I bet they sound great and those tweeter deflectors should definitely rack up some originality points that are important at MWAF.

    Well, it looks like these will make MWAF. These turned out as dual tweeters vs a super tweeter, which sounds much better.

    Note that the diameter of the deflector determines the frequencies that get deflected. A soft dome tweeter is not much of a reflective surface.

    The thread where that concept originated:

    I had to dig for this. A concept I never implemented

    The bracket is going to be sepale to match the veneer. Assuming I can drill a 5/16 hole through 3/4 inch rounded stock, the bracket will be a simple L shape.

    John this is a cool build! As far as the bracket goes, how about 1/2" aluminum..... it could be much smaller and be formed with wood working tools, and you could use Dan's idea of 45 degree front edge. I think that you should be able to find a small piece of 1/2" plate on eBay relatively cheap. Just a thought.

    Yeah, I'm working through the details. Mounting to the box is making me consider other ideas. 45 degree chamfer would allow center mounting of the bracket. Aluminum tubing would good painted, but mounting is bothering me right now.

    I'm with the 45 champer on the edge or use some 1/8" aluminum.
