Ported Box Bracing Q's...

[Boosted92HB 10+ year member]

I was wondering which of the two types of braces would be better for a ported box... Would the first one create too much turbulence and make for weird port noise or "whooshing" even w/ nicely rounded edges? Or should I just do regular 45's. I know that the triangles would be fine, but I believe that the X brace would be stronger. Just looking to get a bit more info before i begin to cut wood.

i've always used wooden dowel rod from one side of the box to the other, i think like 1 1/4" diameter, its been a while.

How big is the box? Its its small enough you can get away with just using the port wall as a brace.

not quite... box is 48" long, so I NEED some kinda bracing in between there...

you can do your x-brace but for ease of cutting it you can do a plus sign instead of an x...if that makes sense. Or wooden dowels connecting the front and back, or corner bracing it with 45's.

if u wanna get real serious, fiberglass resin the inside, use some all thread ( big bolt looking things ) or 2x4s... all spl tricks

The main thing that Im worried about is the fact that it would make for turbulence inside the box from the air rushing through spaces... Will that be a problem, or no?

try the brace in pink it will hold the walls very sturdy and wont cause any problems with the flow of air. just keep them at the right distance away from the port to avoid any restriction of air or cause any noise.

The x bracing will be fine. As long as it is not near the port opening restricting air flow.
