Posted November 5, 201212 yr Just made my first go at this google sketch up and was wanting some feed back to see if i need to make any corrections i'm building for either 3 fi bl 12's or 3 psi platform 2 12's heres a pic of what i have came up with so far
November 5, 201212 yr Looks like you're getting a fair grasp on it. FYI, you can go to the file menu, click on export and export a 2D JPEG image of your sketches for uploading instead of taking a pic of the screen with a camera.Otherwise, you're on your way with it from what I see.EDIT: How much port area is that? That's one measurement you don't have on there and it's looks a little narrow. You might need more port area.
November 5, 201212 yr Author EDIT: How much port area is that? That's one measurement you don't have on there and it's looks a little narrow. You might need more port area.the height of the port is 17.5 and total physical length is 19.25 and thanks for the info i will sure try that next time
November 5, 201212 yr the height of the port is 17.5 and total physical length is 19.25 and thanks for the info i will sure try that next timeI think you missed the point of my question. When I asked how much port area you had figured there, and said it looked a little narrow, I meant the width of the opening seemed narrow. The port area is the height x width. If your port was 3" wide and 17.5" tall then you'd have 52.5sqin of port area, which is likely not enough for those subs to operate without noticeable port noise. Also, your total physical length in that drawing is considerably more than 19.25 inches. The one wall of the port that's measured may be 19.25", the first wall is 15.25" by the looks of the dimensions. Depending on the port width it's more like 36" of physical port length.Where did you get the dimensions you're using in that drawing? How about posting up some more details? We can help ensure you have everything right before you go to cutting the wood.
November 5, 201212 yr Author i was just playing around with the torres calculator and threw some numbers in and did screen shot them but i have a couple that i printed out that around the same measurements that i could take a pic of and post if that will help any.
November 5, 201212 yr Author How much port area would i need so i wont have port noise and what steps would i take to figure it out
November 5, 201212 yr Search the forum for "another bloody calculator". Stefan has a calculator there.
November 5, 201212 yr Author ok thanks will look into that right now i really appericate all the positive feedback
