Thanks for the input, Peter, John and Fred. That's interesting how much you can change the dynamics of the sub(or any ported speaker) by adjusting the port. So it would appear then, to generalize with all other parameters remaining the same...an "aggressively ported" box will have more bass support but drop off more quickly(not as low) and a more conservatively ported box would be a compromise between the two. Would it be safe to deduce that a sealed sub would go lower but on an even more gentle roll-off?
