How big is your box right now, if you made the port longer and it did not change the note the box might be too small. Before we can tell him to make his box bigger or smaller we need to know how big it is right now. Which way do subs face which way do ports face? To many variables......like Tom said you need to only change 1 thing at time and test.

If those are external measurements and you used .75" MDF your box is 5.58 cubes not 7, and this is before sub and port displacement, I bet that the actual NET volume is closer to 4.5 cubes. Which is not bad for one 15" sub. How deep is your port?

ya, those are external dimension's. inside is about 5.6 cuft, including the vent. I think maybe making it 7cuft internal "including the existing vent area would be better suited and bring that tuning freq back to earth, what ya think?
