Guest Posted March 26, 2010 Report Share Posted March 26, 2010 I used 16.75" for port length or is that the wrong number. that 11.75" isnt part of the port? its sort of attached. Link to comment Share on other sites More sharing options...
dwright27 Posted March 26, 2010 Report Share Posted March 26, 2010 Now would you subtract that area underneath the "l" piece running into the box? From the diagram, it looks as if they just took the volume of that square to get 1.02 and not just the volume inside the port? From the dimensions, the volume of the port is .7265625^3ft. Btw, i was using the generic 12volt calculator... i used 23 for port length. 8.75 rounded to 9 13.75 rounded to 14 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.

MrSkippyJ Posted March 26, 2010 Report Share Posted March 26, 2010 I used 16.75" for port length or is that the wrong number. Well it is at least 16.75+11.75. Nothing is drawn to proportion in the drawing, it is rather confusing. The port is 28.5 long (not counting any end correction factor or whatever that is called).

95_1500 Posted March 26, 2010 Report Share Posted March 26, 2010 3.15 after port displacement, so assuming 12" woofer call it 3 after woofer displacement. 15.5H x 3W x 28.5L port which comes out to 34.24 hz Its almost exactly what its claimed to be you wont notice a difference between 34 and 35 hz Dustin, you know you measure the port down the middle right? Not the sides of it Original Build http://www.stevemeadedesigns.com/board/index.php?showtopic=24095 Link to comment Share on other sites More sharing options...

PUNKYOU007 Posted March 26, 2010 Report Share Posted March 26, 2010 If I could ask how much your paying for these designs? Look up "Forum Asshole" on here. He does some great designs and you dont have to worry about it being wrong. You get a 3D CAD drawing and a cut list. Very reasonable on the prices too. Doethepaperboy "Bars of Pain" Doethepaperboy "Hero Remix" C. Arson d(-__-)b beer sucks...but i can bring some jose cuervo. Only problem is that it makes me horny and gives me the rams. So unless yall wanna fight and then have some great make up sex i will leave it home. Link to comment Share on other sites More sharing options...
nCOMP1337 Posted March 26, 2010 Report Share Posted March 26, 2010 out of proportion just sucks, and i would think if the guy sold things online he would have a better way of diagramming these designs i draw all my deigns on graphic paper with the assumed thought of each square being 1 inch, so even if tis not actual size its proportional and to scale then once i get a diagram how i like it, i recreate it to scale in photoshop anyways hopefully those guys helped you out, too many doing the math, i figured id just throw a comment int here to break it up Link to comment Share on other sites More sharing options...
