Posted February 20, 201312 yr I have made a ported box just over 1 cubic foot. This is for a 400rms, 10 inch sub. For a 2.5 inch wide pipe, I need 11 inches long for a 32 hz tune. IS IT OKAY TO USE 2 PORTS? and what type of pipe do I get? Can I just run to home depot, find a strong looking 2.5inch wide pipe, and go from there? and are 2 ports okay to use, even if there the same length? Edited February 20, 201312 yr by Dangercdv
February 20, 201312 yr Yes you can use 2 ports. I bought from lowes 6" PVC pipe an it worked good. I'm sure they will have your size.
February 20, 201312 yr Yes, Just go to lowes and pick up some PVC piping. id flare the ends as well if you know what i mean?
February 20, 201312 yr You can't cut port length in half and use two ports. You need to calculate to use more than one port, you can't calculate length for one port then split it in half.
February 20, 201312 yr Author lol I didnt, I calculated the length for 1 single port... and just wanted to put 2 in.I cant use 2.5, they only carry 2 inch and 3 inch pipe... which would be better? 2 inch pipe needs 6.8 inches long for the port.3 inch pipe needs 16.4 inches long of port. I will probably end up sticking with a single port, but which size should I use? Edited February 20, 201312 yr by Dangercdv
