E8V2 Slot Port Calculation HELP

[slc71 0]

I built a sealed box for my E8V2 using the recommend cubic feet from the website of .25 and the sub just sounds restricted.

Now I am gonna build a vented enclosure for the sub but lost on the port size.

Every calculator that I use shows a 12" (w) x 2" (h) port being around 85" (L) tuned at 35hz with a volume of .6Vb.

That just does not sound right to me, so where am i going wrong?

Any help would be appreciated.

If that is for one 8" that port is a tad large. Using Small's minimum port formula you'll need apprx. 9.75 in^2 of port area. With a .6 ft^3 box that port will need to be 33" long.

Yes that is for one 8" sub. I did not think the calculators where all that complicated but apparently I don't know how to use or interpret them properly.

Thanks for the info.
