"High end speaker covers" do we need them?

I don't have covers and I don't bother to clean the speakers--I call it "dust damping" and I rationalize this as improving the sound.

His covers are very reasonable....after looking at his craftsmanship, l would have paid double if not more....he did my LS50 META covers for 50.00,Revel ultima gems were 80.00 and full length Kappa9 covers were 160.00...l had them made in red velvet with large cursive in gold...he's located in Japan and is extremely knowledgeable with speaker sizing...l couldn't find a single flaw in his work....lm sorry to say the people who l know that do custom embroidery and sewing near me are "hacks"

At first I saw this thread title and said ‘not another way to waste my money’. Then I thought of all the times I’ve had work done at my house- different rooms, etc., that involved sanding, shop vacs, etc… I honestly don’t know that I’d definitely buy them, but it’s nice to know they’re out there. 

Cant seem to find this seller on ebay.

I suppose it's the same reason people cover there expensive cars when not in use......If l hit the lotto and order up a set of candy apple red Wilson Chronosonic XVX speakers with matching pair of Thors hammer subs you bet they'll have red velour embroiderd covers on them....they should be included for the 400 thousand.
