I am building a sub box and I am not sure what is best to use as supports for inside the box. I was told that i could use angle iron but I am not sure if that would work very good.
You can just use some extra MDF you have laying around. It doesn't have to be anything special it just needs to help prevent flexing of the enclosure walls.
You could use threaded rods or similar as many people have done. I don't prefer it but it is good as it is strong but takes up very little internal volume.
how heavy is the speaker, ive never used internal supports just glassed around mdf, but the biggest speaker ive installed were 15kg rockford fosgate t1's the boxes have broken or splintered at all.
does everyone else use internal bracing??
I am using 2 15" Soundstream splx hx subs.
The weight of the sub has nothing at all to do with needing internal bracing. If your box is 14 X 15 X 16, internal bracing may not help you a lot. If your box is 24 X 20 X 48 with no center internal bracing will help you more than you would imagine.

Yeah, the bracing has nothing to do with strengthening the enclosure. It is just for keeping the walls of the enclosure from flexing. Since flexing will mean lost output you want to eliminate it as much as possible. Like idiot said, it is going to be more important when you have large panels as they will be more likely to flex.
ahh i see i see. that makes a lot more sense thanks for the explination
