Is bass the most important frequency band?


One thing I’ve noticed when upgrading my audio system is that when I have really good bass, I’m happy. If the bass is top notch, I can overlook less-than-stellar treble or so-so midrange. The opposite does not seem to be true. Sure, I can get tremendous enjoyment out of a high-fidelity playback of a flute or other instrument that doesn’t have much bass impact, but when I switch to a track that has some slam, if my sub/woofers don’t perform, I’m left wanting, and I am inclined to change the track. When my subwoofer game is top notch, there is something extremely pleasing about tight, powerful, and accurate bass response that easily puts a smile on my face and lifts my mood in a matter of seconds. Maybe it all boils down to the fact that bass frequencies are heard AND felt and the inclusion of another sense (touch/feeling) gives bass a competitive edge over midrange and treble. I am not talking about loud bass (although that can be really fun and has its place), but the type of bass that gives you a sense of a kick drum’s size or allows for the double bass to reach out and vibrate the room and your body. I propose to you that bass and sub-bass should be optimized first and foremost, followed by treble and midrange in order to maximize enjoyment. Thoughts?

It is definitely the hardest band to get right.

It really is. There are so many factors that go into it that are above and beyond the other frequencies. Room acoustics are very challenging at low frequencies and then there’s the challenge of controlling a speaker cone that is putting out massive wattage without it sounding distorted or “sloppy.” Gobs of power and ridiculous amounts of capacitance coupled with high quality drivers seems to help quite a bit.
The most important frequency band is the one you let your mind obsess over.

I’d also agree that it is the hardest band to get right.

I’d also add that because of that, far too many systems don’t even try.

Asking any speaker to go flat down to 40Hz probably also goes a long way to explain the popularity of subwoofers.

No bass is not the most important frequency. I have heard many large panel speakers without the low frequency drivers turned on. They still sound pretty good.
