Hey I'm new to the box building and was wondering if anybody could help me with a sketch or something. My dimensions have to be 34 long, 16 inches wide and 14.25 inches high. I need two ports with 3 inches diameter and 6.75 inches long...with the box fitting two 12's. The box needs to be 2.4 cu ft. Tuned to 40 hz...I'm sorry I'm new and don't know if this is how to post a thread about boxes. All I need is like a sketch or something or maybe wood cutouts or something. Anything would help me thank you!
