i already have the 2 8s and i plan on keeping them forever....

not too sure on what would be best for these speakers but i came up with something like 1.2 ft^3 net @ 32hz. using a 3" round port about 16" long. i am also trying to use sketchup... dimensions are 16"tall, 39"wide, 3.5"deep at the top, and 8.75"deep at the bottom. using 3/4 MDF.
