[QUOTE="RAM_Designs, post: 6836236, member: 566575"] You kinda have to mess with the box size and port opening size to get it down to 38hz, because as you add length in the port of the original design, you're taking away air space, which makes for the need for more port length...it's like a slow cycle that takes a lot of added port and decreased box size to really make a dent in the tuning frequency. 9.63ft^3 is too big anyways, as well as that port that gives you 20in^2 of port per ft^3 of box volume. Go with something like 7.5-8ft^3 with 120-125in^2 of port. [/QUOTE]
