overhang is simple, it's continuing to move after signal is removed.what is reflex? Is it different from bass reflex? I have never heard the term. Is it different from bass reflex?
and yes there are rules that say ported has poorer bass control than closed box. It is simply due to the faster roll off of bass reflex. closed box rolls off at 12 dB/octave. Bass reflex rolls off at 24 dB/octave, 12 dB from box roll off plus another 12 dB from the port roll off.
By the way, Q is conventionally used in reference to closed box. When referring to bass reflex the term is bass alignment.
You really should read a book on bass box design. Try The Loud Speaker Design Cookbook by Vance Dickason. It has relatively simple descriptions of closed box design and bass reflex in the intro to the chapters on each format.
