I have something here that needs fixing ASAP

Well I have this Gigatube stereo that I am borrowing from a family member. That site in the link isn't very descriptive, 55 watts per main channel..lol. We have the higher end model (they made different models of the gigatube series at the time of purchase, btw that pocket too).

Apparently from sitting up in our attic here not being used (yes it was in it's original box however), it appears to have developed a leak in the left sub's chamber. You can hear it when you turn it up anywhere past volume 10, but if I push on the plexi-glass, it stops making a vibrating sound, and it sounds fine from there.

I tried tightening up the 6 screws around the plexiglass plate, underneath the front cosmetic plate (they're actually better designed than it looks from the picture, and produce some of the cleanest notes I've heard from a stereo of it's size). Anyways, that didn't fix things, and being they screw into plastic, I did not want to over tighten anything.

Just today I took the screws out and the plate literally just fell off the speaker (if I didn't explain before, the plexi-glass seals around the front, allowing you to see the sub, but it bounces the bass back up the tube and it comes out there, from the looks of it, it's a 3rd type bandpass box). It looks like JVC glued these things on with something hard and flaky like superglue or something similar.

So here I am now, and I'm wondering what I should use to glue it back on so it makes a TIGHT seal, I have a squeeze tube of this Clear silicone transparent adhesive sealant, would this be suitable? I found this tube after my father handed me a tube of caulking and I told him only a fool would use caulking on a sub, especially one of these pups.

Sorry for the long, long, long post as usual, but I like to try to explain everything up front so I can get a answer sooner without having to wait for replies to "what is that" or lack of specifications, whatever. There's some pictures to enjoy below, don't worry I'm not bugging you guys for nothing :P

Nacho's hit the nail in the head, the only other thing that could work but maybe not as well is hot glue from a glue gun, I've used it to plug a hole in the side of a speaker box before, it got shot. It worked just fine there but there's always a chance the plastic mightn't take kindly to the heat.

I'm not sure I would want to use hot glue on these O_O. These cost my sis like $600 back when we bought them (around 700 after the tax :-( ) and that to us at the time was A LOT of money to spend on a stereo. Especially one that was rated as a "bookshelf" stereo system :S.
Fair enough, didn't realize how pricey they were, nacho's suggestion seems safe enough anyway, I'm about to embark on a little project with a little Alba, making a nice big speaker box for it, a big long one rather than twin, the player unit shall be put in to the middle somehow, but not formed in to it unless I can figure out a way of completely rebuilding the whole front electronics without destroying it...

Hmm.. Do PM me if you need any help/have any questions
Well I have to figure out a way to smash the speaker box open, unless I saw the corner off one side, my main fear is that there could be a little filter for the speakers since it's got a big sub then a much smaller midrange and tweeter, the boxes are heavy so I suspect there's something other than speakers in there, granted there's still only two wires going in.
. Which model Alba's do you have?
I'm not sure, however I'm no longer able to do it with the Alba, now using the Bush which is suspiciously similar, same wonders about the speakers but some new problems to fix, starting with the fact that the Alba player unit was a good bit lighter... they're both reasonably low end bookshelf hifis, we have several, all of which are similar but different makes, I'm kind of looking to have htis project as a low risk practice project, hence why I've been demoted to the bush which is a bit rougher... The Alba I will find out about, we have all the documentation for the junk somewhere but no obvious signs, I'll do a quick google to find out... Some day I might get my hands on the Kenwood...

. Your silicone sealant should do a good job. . Since it doesn't dry/set (it cold flows), caulking is not a good solution.
. And, yes. Get rid of as much of the old glue as you can.

Thank you nacho! I will do. And if all goes well, I might as well crack the seal on the other one and do that too. I'm sitting here right now listening to it just as it is, and the bass just rumbles so far even with the volume down, it's rediculous. Is it just me or am I the only one that's bought/seen one of these units?? I've only met one person that has seen a pair and that was in the store, and he thought they were "just okay" too like I do. But meh, I'm happy this stuff will work.
