Qts 0.43

DCR 7.2Ω

Load both subs in a single enclosure, either sealed 2.3 cuft net, or ported 4.8 cuft net with port tuned to about 25Hz. The subs can handle 300 watts each.

I'm a noob when it comes to how to determine a box size + port size. If the box is 4.8 cubic ft with a port, what should the demensions be LxWxD ? how wide / tall / deep should i make the port?
