Okay I just finished designing my first ever ported enclosure. The box is 2.4 cubic feet tuned to 32 hz. I will scan my drawing and post it on here tomorrow morning but for now here are the specs:
External Dimensions: 35w, 17.75d, 14h using 3/4" MDF
Net Internal Volume after ALL displacements: 2.403 ft^3
Port Area: 46.875 in^2
Port Length (measured along port centerline): 43.5 in.
The tuning I know is not exactly 32 hertz, but it should be pretty darn close. Like I said, I will scan my drawing in and then post it on here tomorrow so you all can make sure I figured everything correctly, but do the figures I posted above sound about right?
