I'm currently building a sub. It's a sealed box, and the sub I'm using is a Dayton RSS315HO-4. The box that I'm using has the sub frame flush with the outside of the box, but the surround sticks above that, about a 1/2" or so (I haven't actually measured it at this point). I'll need a grill on there because we have a cat, and who knows what she does for entertainment when we're not around. My grills will be of the plywood framed type, with lightweight grill cloth covering them.
My question is this: How do I determine how far away the grill needs to be from the sub surround, so that I'm sure that it never hits it? I know what XMAX is on this speaker is 12.3mm. I'm assuming that even if it were to fully extend 12.3mm, the actual surround wouldn't move that much, since it's basically stretching a radius, so it shouldn't actually move the entire 12.3mm. But, I want to make sure that I have ENOUGH clearance in there so that the grill cloth never touches the speaker...
