crossover lower with ported?

I have been working with the ported.xls program from

When I insert a 80hz 12db crossover the frequency plot shows the rolloff starting about 30hz lower (50hz.) It does do this on a sealed plot.

Is this correct does a ported box effectively lower your crossover point? This would be a real advantage if you have a reciever with too high a crossover.
