Regardless of box size (cubic, or rectangular, or whatever), if you keep the same port area, port length, and volume, the tuning will be the same. Gotcha, I will play with their design a bit tomorrow. Quick question though, I pulled up the sketch up file and noticed this strip is higher than any other part of the box. Having trouble visualizing if this is a front ported or top ported box. What height would be used for port volume? Link to comment Share on other sites More sharing options...

Having trouble visualizing if this is a front ported or top ported box. What height would be used for port volume? I suspect that strip is an error in the Sketchup model. That panel should probably be the same width as the other panels (14"). The box is front ported and the port dimensions are 14" tall and 2" wide.

dryvr12 Posted November 10, 2017 Author Report Share Posted November 10, 2017 Ok, I put the SA box design into the calculator just to verify. Am I doing something wrong here? Also is the port length on the pre-designed box = 30.75" (1 1/4 + 13 + 16.5)? Just want to make sure I understand the port length dimension Link to comment Share on other sites More sharing options...
Wasteland_Audio Posted November 11, 2017 Report Share Posted November 11, 2017 Delete the number of ports and the diameter and leave them blank, it's throwing off the calculations. Link to comment Share on other sites More sharing options...

Just want to make sure I understand the port length dimension The port is going to be longer than that because you measured the length of the panels, but port length is measured down the center line of the port. I can't tell what it should be from the pic, but its going to be several inches longer.
