[QUOTE="Jeffdachef, post: 8671497, member: 650438"] I'm guessing you are completely new to ported boxes. The port changes depending on your cubic feet airspace, you dont keep whatever bullsh*t they recommend because its beyond stupid recommendations. box size and port size, length have a direct correlation with box tuning, power handling, and bandwidth. I'd recommend youtubing up how to use winisd and download torres box calculator and get proper box numbers with projected response graphs, rear air velocity etc... like so. You just need enough port area to avoid compression and get the tuning you need which will be rear air velocity values on winisd. Too big of a port and too small of a box will literally make it absolutely impossible to get the tuning you desire and you'll still end up in the high 40s port tuning.
