Hi, Quick question about PR's: I have 2 of the Stryke 15" PR's, with the default plain black diaphram (not the foam all the way across like the Adire PR15). They look nice, but I'm maybe looking for a more elegant look to the finished project, so I'm wondering, can you cover the diaphram in some other material, as long as it doesn't hit the surround? Could I cut a circle out of matching veneer to the cabinet to cover the PR's? I know it would add some mass to the diaphram, so I'd have to take that into account. What about just covering the diaphram disk with grill cloth glued right to the disk itself? Would this mess up the PR's functionality? Thanks, Wes ps sorry for all the questions, so new threads for a while, I promise (maybe. . .) you guys are just too helpful!
