Sub enclosure problem!! NEED HELP!

**bboy eclipse** · 12-09-2006 05:23 PM

Hi guys

I was just wondering if anyone has advice on fixing a sub enclosure problem. ATM my sub eclosure has an area in front of it where plexiglass should go. (PIc below). Once I put the plexi glass on, the bass of the subs seems to much for it and the plexiglass rattles like hell and its bloody annoying!!! I was just wondering if anyone has any ideas to fix this problem? I have been told that drilling holes into the plexiglass will fix the problem, but i want to know if the have to be a certain size? or amount. I thouhgt i'll seek advice before drilling random holes in it and ruining my plexiglass!!!. If anyone has this knowledge please post it here.

Thanks!

Here the pic of my sub box

Screw it down harder, or the area must be too big to support the movement.

Your best bet is to use thicker plexiglass.

Yes, as others have said thicker plexiglass or perhaps trying a material like macralon, which is like a perspex material but much easier to work with. It kind of works like wood.

I'm not sure with plexiglass, but with perspex you have to be carefull when working with it as it can crack very easily when being drilled through. From my experience using a drill bit designed for brick gives better results (sorry the proper term for this sort of bit has just slipped my mind).

You could also try putting some bracing across the front panel, but this may not be the look you're after. You could try incorporating the bracing into the design by putting thick aluminium bars across the front and lining the inside of the enclosure with diamond checker plate would give a cool industrial look to your enclosure and provide extra support to the front plexiglass front panel!

18mm perspex i bet it wont rattle

Thanks guys for your suggestions. I was thinking about screwing it in tighter but i fear i may crack the plexi glass which is the last thing i want to do. Putting brace sounds like a good idea and so does thicker plexi glass. Anyways thanks for the help again and if none works, i'll just yank it off! lol

Have you got anything else securing the plexiglass? Or just the screws? It all depends on how big your window is. If your pictures worked it might give more of an idea...Or even just post up the measurements and I'll think of some way to help...

As stated b4 dude the pics would be a big help for everyone....but just hazarding a guess...(pls b4 flaming me ive had after work drinks tonight ppls).....and as an easier solution have u jsut trie additional screws.....if the distance between ur fixing points is to large then the material between these points will rattle.....if you dont want to screw ne extras then maybe use dynamat or another sound deadening product and cover just the part of plexi-glass that is touching the rest of the box to kill the rattle......still dude remember these are jsut guesses cause without at least pics none of us can really give proper advice to help with the problem

Hey. Sorry guys i thought the pic was working, i will try and fix that problem. As for the plexiglass it is 40cm width and 29 cm height. It is also about half a cm thick which im thinking that may be the problem that it is too thin. currently i have used 18 screws to bolt it down. I;ve tried and attach the pic again
