I don't think anyone is actually suggesting this. Bass is an important part of music but put a Real Time analyzer in the room and play your favorite album. There is vanishingly little music that happens below 45hz so a speaker that reproduces cleanly down to this point typically sounds like it has amazing bass response.
As we proceed to lower frequencies the room tends to get in the way and reproducing a 27' LF waveform in a 20' room stacks up into standing waves and turns to mush with a lot of hot spots and dead spots. Faithful reproduction of the music is lost. It is completely subjective at this point whether you like/don't like the LF effect and I am not one to judge another's preferences, but I subjectively want my bass reproduction clean with as little mush and rumble as possible.
Most subs typically cross over at 100-120hz and fill in a lot of energy between 40-120hz. We sometimes rent powered subs for outdoor live shows and their useable response is 47-100hz. These add a ton of bass energy right where we need it and there are no boundary issues causing flutter or standing wave mush. Just huge clean chest-thumping bass.
