Brian,If you look at the transmission characteristics of various fabrics, you'll see very little absorption at 1-3 kHz, and quite significant amounts at 10 kHz and above. Playing around with a graphic equalizer indicates that the extra fabric rolls off the high end starting at around 4-5 kHz and increasing smoothly to around -3 dB at 15 kHz. It's a fairly subtle effect and not noticeable on a lot of instruments.
As I indicated in my posting, I'll be trying other solutions; but the extra fabric layer does seem to work the way I want.
Like the Advent grill, the Polk grill works on diffraction effects by being a smooth transition from the tweeter mount to the beveled edges of the box. The Polk fabric is really transparent and is mainly cosmetic.
