[QUOTE="SSS 18734, post: 5662093, member: 559710"] This design is for team3d and his pair of 18" HDC3's. I'm trying to get better at designing boxes in Google Sketchup, so critiques/comments are welcome. To be exact, it is 9.92 cubic feet tuned to 33.3 hz after all displacements. There are 85 square inches of port. Step 1 - I left enough clearance for you to use flared aeroports. I'm not sure how to draw them in sketchup. Those guide lines will get you the center of the port. [IMG]http://img24.imageshack.us/img24/2879/step1s.jpg[/IMG] Step 2 - if you choose to brace differently, the brace displacement is .25 cu.ft.
