And, our hearing sensitivity significantly drops off at lower frequencies. To sound as "loud" as higher ones, bass must be played at higher SPL than almost all woofers and subs are capable of producing (the lone exception being the Eminent Technology TWR-17 Rotary Woofer).
I have long found reproduced music to lack the weight and visceral physicality of live. At live shows, we feel the music, not just hear it. It's a full body experience, not merely an aural one. Of course, we have to temper our expectations, as recreating a symphony orchestra in one's living room is "sort of" impractical.
