Well I am building a box for my 15 inch fi SSD I will be feeding it 800 watts


Are these supports in the box really going to do anything? I forgot to buy the wood for it. I guess I could go back and get them but I figured id ask first.

not really.
don't think the SSD would cause much flexing of an enclosure.
don't take my word for it though.

no the back side we were siting in his car and you could hear it pulled the glue and screws right out and

I'd say it's worth it, it would **** if you blew a side off the enclosure because you forgot the internal bracing. The bracing helps stop the walls from flexing too, if your competing flex will hurt your score.

Can I use any wood really? If its not circle like that will it effect my tuning at all? Probably a stupid question just making sure though.

depends on how big those unbraced panels are...I'd definitely do the one from top to bottom.

Also, the baffle should not be sandwiched between the top and bottom pieces when there it so little clearance like that...it should overlay the top and bottom pieces in order to gain much more strcutural integrity.

i would just go get one thick dowel rod

Alright I am trying to make this box perfect. Going to carpet it and everything so I dont want to do a half assed job. It would **** to have it blow apart on me.

I already cut the wood ****....do you think this will be an issue?

Baffle won't be an issue. If you're really concerned add a small wood block top/bottom behind the sub opening.

I'd add braces as the box looks pretty big as it definitely won't hurt and it's only $5.

the box is 26x27.5x16

Also I am planning on using a jigsaw to cut out the circle. What is the best way to trace the circle out on there?

It shouldn't make any noticeable difference to the tuning of the enclosure. They suggest round bracing because it helps the flow of the waves, flat edged supports make sound waves bounce back where as a round support the waves can flow around and past it to the port opening.

Get yourself a compass and draw out your circle. Get one at a dollar store or something.

For that enclosure, nah, ya don't need any bracing for it.

If the parts are cut clean, true and square and assembled properly, I highly doubt you got anything to worry about. Cut it, build it, don't sweat it.

Its already cut. Cuts are very clean and line up almost perfectly

what happened to the theory that once the glue cures its stronger than the wood? ****** glue, or did he just not let it cure before using it?

probably used caulk or gorilla glue or some thing

id not worry about bracing it.

hell my 16 cube wall has no internal bracing.

Insurance is only necessary to protect yourself from the rest of the idiots on the road.

*****, auto insurance wasn't a requirement in the state of new jersey until 1972.

The bond is stronger than the wood itself and I highly doubt it exploded due to the pressure the subwoofer created. A good, well built enclosure with good bond joints, you need a 2lb hammer to beat it apart or drop it from two stories up.

To the threadstarter, no, those dowels will do next to nothing for structural support.

85% fact. I only say that because MDF is special in that it doesn't exactly have wood fibers (I'm talking about running the length of the board, not the composition of the wood itself), but it still holds true. Particle board is very hit or miss though. When I tested all the Titebonds, and Elmer's carpenter and probond, all 5 never broke at the joint when properly clamped.
