I had a lot of fun building a 'proof of concept' skyline diffuser out of 1x1 pieces of wood, glued to a piece of plywood. Came out looking awesome, but too small to be effective, and heavy as shit! I didn't use any kind of calculator, just made 1,2,3, and 4 inch sections and randomized as best I could. Concept proven? Only that wood is too heavy.
Think Balsa Wood!Jim
Holy. . Mackerel. This stuff is so fun. Just got home from poker night and hung the single skyline a couple feet above my bed. Now, tomorrow night I'll have three of these.The giant QRD is, as I said, providing huge dividends on that back wave, but I've been doing little tests as I go along and one of them is I clap my hands upon entering the room.Even with my QRD, upon entering the room many feet from those and clapping my hands revealed some ringing. I just clapped my hands with this single skyline added opposite the QRD, near me, and the clap sounded like it was coming much more from my hands, less from the echo. There is still some ringing, we'll see how that improves tommorow with two more.
For a 2'x2' panel, the 2"x2" pieces are:38 pieces - 1 7/8" 38 pieces - 3 3/4" 40 pieces - 5 5/8" 15 pieces - 7 1/2"(This includes space for 13 blanks - 0").
RC, can you compare the QRDs with the same size of Skyline panels behind your Maggies?
Hi Rclark and all Audio Circle members.Your project is super interesting for me and I am sure for other Audio Circle members.Styrofoam here in Vietnam is inexpensive. (Super cheap)Did you make the small styrofoam parts from a big board, let say 4' X 8' ?Please let us know where you have hang up the diffusers in your room.Guy 13
