We're so accustomed to distorted bass that very clean low extension may sound weird. With speakers it may be even a bit dull, like large Genelecs or good quality open baffle (which is a bit different in other aspects as well). Also, in live events bass is rarely clean. And when it comes to recordings 20-30Hz is mostly in the effects and may come with huge distortion added already in mixing.
For me totally clean bass sounds a bit unnatural but fortunately my choices in music make all this quite moot.
I think, dawn., you should make a trip to a shop for a day and just have a listen.
