Here are the T&S parameters needed for the ideal ported enclosure, if you think you can just throw a sock in the port and have a sealed (IB) enclosure to suit the same driver, your nutz.

But to me if "big enough" with driver "that suits" an IB box, then you have a "better lower tighter bass"
Nevile Thiel (rip) helped me make two huge 12cu.ft ported enclosures (about the size of two large fridges) for two very rare massive Kef B1814 (flat diaphragm pis-tonic motion) f/s 20hz drivers I had.
These bass units got used from 100hz-18hz flat. While serving me very well with Accustat 2+2’s as mains, those huge bass bins were shamed a few years later by the majestic ACI SV12 f/s 17hz drivers in sealed IB enclosures 100-20hz, the speed and the concussion into the kidney region couldn’t be match by those ported boxes .
