Cynner Posted August 10, 2010 Report Share Posted August 10, 2010 (edited) Hi Guys, Having a bit of trouble here. My box size; 38" Wide 35" High 25" Depth 1 30" Depth 2 I was going to tune it to 33hz unless someone thinks I should tune otherwise to something more / less. Running 3 kicker L7's but currently have square ports currently but was going to convert them into Triangle thought it would look a lot better. I'm going for pure SPL not SQL in the least. Can someone help me work out the sizes? I've tried doing the math it's fairly simple but for some reason I dont think I'm doing it right. Here is the current box, this was a picture taken last weekend. Its not even close to done. Thanks in advanced, hope someone can help.

Gingeriffik Posted August 10, 2010 Report Share Posted August 10, 2010 (edited) I think the most simple way to do this would be to do the port calculations with a sqare port. Once you have the proper dimensions of the square port, you can use that area to determine the area of a triangle you need, and you wont need to calc. the length because your going to be using the same port area as befor. Just a differnt shape.I recomend using this calculator, verry nice tool.

Gingeriffik Posted August 10, 2010 Report Share Posted August 10, 2010 (edited) Just FYI the equasion for finding the side of a equalateral triangle based on the area is a re-work of K=a2(√3/4) Where K=area and a=side of triangle. The re-worked equasion is √((4/√3)K)=a. I say use and equalateral triangle because all you have to do is find the width of the trianle and cut 3 boards to to the width(+7/8" to compensate for the miters assuming 3/4"MDF/Ply) and length and put opposing 60 degree cuts on all 3 and put it together. Ex. Say you find your port lenth to be 18" and width from equasion to be 7" on the dot. You would cut 3 boards(3/4" assumed) to dims of 7 7/8" x 18".

STEvil Posted August 11, 2010 Report Share Posted August 11, 2010 two triangle ports, one in each top corner? Would be badass. Flare the end in the box so they're more efficient.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

speedball1978 Posted August 11, 2010 Report Share Posted August 11, 2010 lol ok let me try to explain one more time lol since you have 2 squares... to convert this to a triangle, the port length can stay the same or be longer to maintain the frequency, but the length of 2 sides will need to be stretched out...so if your square sides were 8 by 8 then the triangle would be somewhere 11 or 12 inches on 2 sides and then whatever the lenth of the 3rd side ends up will be automatic Quote Link to comment Share on other sites More sharing options...
kowboy Posted August 11, 2010 Report Share Posted August 11, 2010 Why not figure out square ports, and then just turn 'em on their side and make them diamond ports?...should still look pretty unique. Quote Link to comment Share on other sites More sharing options...
Cynner Posted August 11, 2010 Author Report Share Posted August 11, 2010 good idea with the diamond ports..

speedball1978 Posted August 11, 2010 Report Share Posted August 11, 2010 i told him about that in his other thread he started... turn the square ports around into diamond ports... guess he didn't catch all that Quote Link to comment Share on other sites More sharing options...
