Finally figured out the SU equivalent tools to the CAD program I'm used to, so I modeled up a box for my 18"
Building should hopefully begin Tuesday. I'm probably not going to paint it, thus the design on the double baffle will probably be omitted, but everything else should be the same. The box is 6ft^3 tuned to 34hz with 97sq^2 of port area. Will be housing an HDC3 18 to be broken in on 600w and will eventually be run daily on 2000w.
