yes, in a 2.25 ft^3 box with a 5"x 22" port you will be tuned to approx. 30 hz. This was using winisd. Should be little or no port noise and gives a pretty good looking response curve.

^exhaust pipe for trucks. works quite well and if the shop has a pipe bender you can even get mandrel bent lenths that are longer than the box,right then and there otherwise they have to send it out. Usually I use slot ports anyway.
