I'm going to be porting my 12W7 enclosure. 2.9cuft tuned to 28hz, twin ports at 2" diameter. According to an online calculator, the ports should be 7.45" in length. This sound right to everybody?

using WinIsd pro. 2.9 cubic foot box ported to 28 hertz using twin 2 inch ports calls for a lenth of 5.95 inches. Or if using a singe 4 inch port a length of 11.91 inches.

do not..i repeat do not..use a port that is 2 inches small...you will have the worst port noise known to man...best bet is to use a slot port on the side...or if you absolutley have to use round ones....use 1 big one, not too small ones

If your stuck on using round ports, I would recommend dual 4".
