you do gain something from 5Hz to 7hz

Probably not. That would be the rising plot situation we talked about sonnie, caused by the mic calibartion file compensating for a signal in the noise.
Those two plots are correctly responding to the situation.
The gold line is acting like a proper vented system. As the frequency approaches the tune, the output rises and then drops off quickly below the tune. You've gained where it's important.
Without the vented port, the green line represents an IB again and drops down at 15Hz.
I think both plots are enjoying room gain, although I don't really put much faith in any plot line below about 10Hz.
