Port And Bracing


Recommended Posts

Posted

So ive seen a few people put bracing in their ports. Does this affect tuning? I am looking at doing 2 15s sometime this year, then going to 4 15s. For the 4 15s i would run subs and port up, will post sketchup drawings in a second. I was lookin at LVL4 15s. Was going to give them about 3 cubes each (what it says on the website) tuned to 30 Hz. The box will be 38w*35d*25.75 tall (2x baffle on top) For bracing i would use some 1" dowel rods. But i was also wondering about bracing inside the port. The port on this box is 5" * 33.5". I was thinkin of using some dowel rod to brace the inside of the port too, pics up soon

You might be a Redneck if you use your leftover gutters for a speaker box port...

You'll be fine bracing in the port like that. It doesn't take up very much airspace so it's not a big deal. If you were trying to brace it with 2X4's then I'd say that you may have a problem, but dowel rod is a great brace to use. I actually prefer dowel rod over pretty much anything excpet maybe threaded rod. You really can't use threaded rod to brace a port, well you can but it would be a pain in the ass.

this build wont happen for a while, but if a friend should ask me to make a box for them or somethin, id hate to do something like this and have it fuck up the box. Im thinkin 4 LVL4 15s, (designed a box for 2 also) probably start at 2 then save up for 2 more.
