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.

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.

So I am building a center console for my F150 that will have two E8V2 in it. With the cubic feet being .5 I put together something. My only question is there a issue with having the magnets back to back as in the diagram below (not touching). Sorry for the mspaint crudeness.
