A dowel or threaded rod will not "mess up" the airflow enough for it to be noticeable...now if we are talking about 2x2's or 2x4's that is a different storybracing works alright but maybe he is like me and will not use it as it can mess up airflow?
I still doubt you'd notice a difference if you had one enclosure braced with a 2x4 and one not, both having equal net volume. Other than the 2x4 box not flexing. As long as the 2x4 wasnt blocking the port or something.A dowel or threaded rod will not "mess up" the airflow enough for it to be noticeable...now if we are talking about 2x2's or 2x4's that is a different story
I use scrap pieces of MDF to brace my enclosure, the pieces themselves are usually 3/4 x 3" wide. Not once have I ever heard anything remotely close to interference from the bracing. The only time I can see an obstruction like that causing any problems is if you built a burp box, since you want the least amount of resistance possible (both in your enclosure and your electrical)I still doubt you'd notice a difference if you had one enclosure braced with a 2x4 and one not, both having equal net volume.

Good toknow for the future lol. I already paid for the design from RAM so ill prbly just do it that way. But if I was going to do the bracing on this I would just build my box the same as he says but just not put the extra walls on each side? But I could still put an extra face on it because I want to flush mount it. Then just put those screw in poles in? Correct? Cuz ill have enough extra wood left over from my past build that ill only need to buy one sheet.If you double wall an enclosure you will lose volume if you are limited with space. Best option is to do a single layer 3/4" enclosure with good bracing. The OA15 is a great sub, but it is not going to rip apart a single layered enclosure that is built properly.
