Is adding bracing to the smaller sides pointless?

how much should I add?

sorry searching didnt provide good enough answers for me

What I usually do is cut a square piece to fit inside the box. Then I cut a couple little squares out of it. Round over all the inside edges and put it near the middle.

hmm I dont think I could do that unless I did two of them and that sounds like a lot of work...is that a lot more effective than boards connecting the sides?

Do you have pics of the enclosure, or a plan? Would be a lot easier to say WHERE to put the bracing.

As far as the bracing material: Home Depot has some great thick dowels in the molding section.

exact enclosure

i have a mag in it and i can hear the enclosure vibrating bad, its killing output

i saw dowels today but they were like 5 bucks for a few feet

cant i use 2x4s or mdf?

bump, is there any disadvantage to using 2x4s besides displacement?

Bracing isnt really needed, its an over hyped step that most people on CA.com feel needs to be done.

i had a box tuned to 30hz and for me anything above 45hz sounded horrible and this was a very solid box!! Anytime you play to high over your tuning its going to sound bad
