On a more serious note though, glad that is working for you. I tried something like that and the "airiness reduction" effect is even more prominent than with the fabric from the stock grills. It's hard to describe it, as it's not even airiness, more like the background nuances...the only adequate description is from 6moons writeup:
"While cosmetics do take a hit—you'll see exactly what the final photo shows which is now barely obscured by the open honeycomb pattern—those fine decay trails and reverberations that were previously obscured (killed by damping as it were) are now released. This has nothing whatsoever to do with becoming sizzly or sharp. It's all about the restored breath of life. Things which previously felt somewhat flat, reined in and muted open up. Recorded ambience deepens and with it, spaciousness."
It's a subtle but dramatic improvement that you can't really pick up with analytical listening.
