It is not only that manufacturers cannot get bass extension from small woofers but often they don't want to (tuning bass for lowest distortion and not for extension). Paradigm Studio/60 v3 has worse bass extension than previous Studio/60 v2 but sounds better (according to reviews). My Hyperions HPS-938 have pretty large box with two 8" woofers but only 35Hz extension.
For practical reasons I prefer better bass definition over extension since lowest bass string is 42Hz and below that are only pianos (keys seldom used), big drums (mercy for the neighbors) and church organs. Extension can be remedied with a Sub but loss of bass quality perhaps not.
