Speaker excursion

[MastaST]

Hi, I've got two Phoenix Gold Ti12's in a sealed box. (1.25 cubes per chamber).

I've noticed one speakers excursion is noticeably going further than the other. It also seems distorted. When I push down on the outside it seems to go away, so obviously it's a problem with the seal. When I rescrew it it seems to go away for a bit and then come back.

How can I get this to completely seal? Are there any special screws I could use? Is there a type of caulk/sealant I could use?

Thanks

Did you glue the box together real well when you put it together? I'd probably glue it real well and then when that was dry use something like silicone caulk all around the insides. Just remember not to put the sub in until the silicone is finished curing otherwise the vapors can hurt your sub.

No, this is a q-logic box. It's caulked/sealed fairly well around the seams.

I cannot get the actual subwoofer to seal properly. Could I caulk around the outer edge of the subwoofer without damaging it, or would the caustic fumes ruin the sub? If not that, are there any alternatives to caulk?

Why don't you just drill new holes for the sub? It sound like the holes are just stripped out.

I seen on this forum somewhere that someone suggested T-nuts. look 14 threads down for the link.

most subs come with some sort of a rubber/foam ring that you stick inside the frame before screwing it onto the box...ensuring a perfect seal, kinda like a gasket....you can get the double sided tape or something and sandwich in between. sometimes the outer rubber gasket also becomes unglued... check that for leaks as well..

hope it helps...
