The lowest note produced by any orchestral instrument is 29Hz, from contra-bassoon, while piano goes down 27.5Hz. Actually, it only rarely that those instruments get down that far. When they do, fundamental is very weak anyway, and most of the character is imparted to the tone by the harmonics. The lowest harmonics, which is the second, is in the above cases 55Hz and 58Hz respectively! The bass drum is about the only orchestral instrument that really needs a deep bass response to do it justice, as it has few harmonics beyond the starting transients.
To reproduce down to the lowest frequencies, it is by no means essential. In fact, SUB-bass response it reveals nothing but the rumble! Bass response within a few dB dowen to 45Hz can be considered desirable to give depth and richness to the reproduction, little is gained by going lower. And even higher limit can often be preferable to a lower one gained at the expense of naturalness. Also listening room dimensions may not permit the propagation of bas much lower than this anyway.
