Sub enclosure inside a Camphor Chest

[qguy]

Thinking about building a sub enclosure inside one of these , assuming I can get a decent looking one of the correct size and price .



1. Will be using 3/4 mdf with bracing.
2. Sub would be downfiring.
3. Legs would be added
4. Plate amp would be mounted on top, The top cover of the chest would still be usable to access the Plate amps controls.
5. Holes with small fans would be mounted on the back of the cover
6. All MDF side panels would be glued (using epoxy I guess) to the side panels of the chest
7. The original bottom hardwood panel would be removed.
8. Will be installing 12 or a 15 inch subwoofer for this project

Any issues, I was thinking the top cover might vibrate, but with adequate internal bracing, this "should" NOT be an issue ? right ?

Do you thing MDF bonded to the hardwood with epoxy will last "forever" ?

if you can get rid of vibration, then it will be just okay
epoxy might be overkill. there are nice gules out there for woodworking, suposedly that should be more than enough.
if you would like the top cover to stay functional you have to somehow get rid of its vibrations.
probably some sponge like material between the surfaces might work just well.

You'd be better off buying a good sub and covering it with hardwoods!!!

I think you may be better off building the woofer box independent of the chest but with an oversized baffle to fit in as the new bottom. You may have trouble bonding to the chest if the interior has a finish on it as the one in the photo. Building a separate box means you have leeway in the size of chest you purchase.

Yeah, I'm with Cal, I'd probably build it to the size that's needed for the driver and then fit that into the chest with leeway around it. Add some foam or something of that sort between the cabinet and the chest on the inside.

Edit: Or even Great Stuff, if you never plan on removing it.

I would float the subwoofer box and driver inside the chest using the padding that is used for gymnastics. It's a very soft foam rubber that is very heavy.

Also I'd make a new bottom to set the foam rubber on with a hole that is larger than the driver so that no parts of the inner and outer box are shorting.

edit: with a hole cut in the rubber as well...
