So, I got a Velodyne ULD12 sub that needed the surround to be re foamed. I got it for free, so what the heck. I bought and am performing the reform but it appears that the outer, hard cardboard gasket, is missing. I was thinking finishing up the job, hooking it up and buy and install the gasket later.
Question, is it necessary to have the gasket at all? Can I connect it up and put the gasket on later? This would not harm the new surround, right?
