Are these supports really nessesary

[SPL Blazer 10+ year member]

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.

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.

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?

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

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

what happened to the theory that once the glue cures its stronger than the wood? shitty 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.

Sh!t, 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.

Then it simply wasn't built properly.
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.
