Seal between MDF ring and subwoofer

Okay, this one may sounds dumb, but i was wondering about it while makind my MDF rings.

I get the point that when you put fiberglass over the MDF ring, this create a seal so no air is leaking from the outside of the MDF. And i suppose that when you glue the 2 pieces of MDF together to make a ring, the glue create a seal so no air is leaking between the 2 pieces.

My question is, do you add something between the subwoofer and the MDF ring so no air leaks from between thoses two? I guess not, and i've been looking over the net but didn't found nowhere that talks about this, but maybe someone already tried this and can tell us his experience.

Or maybe i'm just crazy thinking about something like that :p

most subs come with a rubber trim ring. they also make a butal rubber you can seal them with. and alternatively you can use weather stripping from home depot

I generally use a bit of rtv silicone to seal this area

if the box is carpeted it will help as well but make sure there is something there or you are liable to hear the sub whistle when air escapes it

So it's a good idea to seal it... That's good news

Thanks all!

I've used the weather sealant before as well. Also, you may want to try and get a hold of PG to see if they can hook you up with some rear gasket material (They did it for my xmax's thankfully!)

I have used the stick on weather stripping with success. I've also used the RTV silicone sealant before too, but it's hard to get off the sub when you decide to change.

Thanks!

I'm trying to find a rubber that would fit cleanly here, if i can't i'm probably gonna use the tape seal.

they sell a foam tape that is used for sealing doors at most hardware stores. Get it as thin as possible and it will be no problem.
