yeah it is stitching, but i think they may have glued it because it doesnt move at all. it is stuck there.

P.S. i Just ordered these. (price sounds great until you check them out. i paid almost 70 bucks out to door. 20 bucks shipping and handling) Can anybody give me a link of nice, powerful subwoofers that will fit right in? I would like to pick a set of those as well. Thanks.
