i have built a couple boxes in the past and all of them sounded really good but they were all sealed. they were sealed due to my lack of knowledge in knowing how to tune a port. i was wondering if anybody has a program that will diagram a box for you if you put in the dimensions. if so could you post it. also was wondering about how to tune a port, is there a program or just a formula. i got winisd but have no clue how to use it. if any one can help i would really appreciate it.thanks
