Hey guys I just picked up a DC Level 6 18 m3 and I created an enclosure after measured everything out and came out with enough space to fit an enclosure that's 24.5 x 39 x 19.5/20. I wanted to do sub up port up because there is not enough room to be able to do port back because it is always smashed against the hatch since the hatch has a curve to it. With the design and 2 "6 aeros I wanted to tune to 27 with 18" per aero including the flares. If i do it that way then i come out with the end of the flare to the bottom of the enclosure either 1.5 inches if I decide on 19.5 inches tall or 2 inches if i decide on 20. The question is is either enough distance from the bottom plate to allow for the sound to travel?
