[QUOTE="Buck, post: 8750239, member: 591582"] It's bracing. I wouldn't do a brace like that on too small of a port. Why I do that is just to keep the port walls stable and from flexing. The port walls can be hard to brace unlike the sub chamber. Ports have to be fairly exact to get the tuning right and not disturb the airflow in the port. So, doing a port brace like that works well, in some situations. The port opening into the environment is one of the weakest standing walls, because it's only attached on 3 sides. It's silly to me to run a box like that Orion 12's box with 5000 watts and not have any bracing on the port wall, when the rest of the box is beefy. At a certain level, I like to just double some walls up. But, that adds a ton of weight and usually bracing is more effective, from a wood-mass and cost level. [/QUOTE]
