Ok this is what I got so far I plugged all into torres and got the following 19.25 box width 9 H and 12 D. My port dimensions are 7.5 H and .5 Wide 13 long puts me at 34hz this port ratio is 1:15. Is this bad? This is for 1 Sundown Audio E-8 or SA-8 . My net volume is .58 cubes. The actual box will be 40 but putting in port wall leaving it 19.25 w per enclosure space. Thanks.
PS. I also calculated .10 for sub volume I noticed this on sundowns page for the E-8 but it says the SA-8 is only .08 strange would think the sa would take more room.
