I have made a D.I.Y version that I use in my 2 channel system. I use a 8 1/2, and and a 10 inch round Aluminum lamp shade. Thus the name was born " Sound Shade". I do have them modded with solid brass cap on a solid copper fitting in the center hole where the light bulb would be.
The D.I.Y Sound shades work just the way Rnwong described. My knock-off D.I.Y version both open's up the sound field and focus the music. The sweet spot is much larger and detailed. There is just way more music coming at you.
If removed you will want to put them right back in. The difference is that noticeable. I have pictures of them if you click on my system.
Without the copper fitting and the Brass cap on the end they do not sound nearly as good. There's a tweak or two you can do to make them work even better. If mine work this good, I know the original must work just as good if not better.
