I built these speakers almost two years ago. The plans showed a bass port, but no port tube. Is one needed for the 2Pi towers? If so, what should be the length.
In case the wood panel isn't of the same thickness (this being the port length, in case there was some differences) of the original Pi-Speaker project, you can recalculate the diameter of the port, for the same tunning frequency.

That's right. The plans show port diameters for 5/8" or 3/4" panel thickness. Others are shown here:
For 5/8" wood stock, cut a 4.5" diameter port hole.
For 3/4" stock, cut a 4.625" hole.
For 1", cut the hole 4.75" diameter.
For 1.5", cut the hole 5.125".
