Why so obsessed with bass?


Such a obsession to deal with bass issues.  Why is this?  
On a sub if there is too much rumbling simply turn it down.  
As far as mains these probably are not much of an issue for most of us.  However for bookshelves speakers it makes sense they really aren’t well designed for lower range frequencies.

Why? You have your answer:

Good bass response transforms a system.  Everything from classical to acoustic guitar sounds better.  Deeper, wider soundstage. 


So true. The problem is we still have lots of people who never heard good bass so have no idea what they're talking about, saying crazy uninformed things like
The only recordings to contain subsonic energy are a few digital made since ’85.

Well that's odd, because just the other night I was listening to some Tchaikovsky and at one point the AC or heating or something came on and was clearly heard and felt and you knew that's what it was not anything else and this was recorded something like 50 years before 1985. In fact this sort of low frequency information is on a lot of recordings. Its just everyone has crap bass so they never even know about it. But it is there. On probably the majority of recordings.   

Its really sad, borderline pathetic, certainly perplexing. Vexing. That's the word. I am vexed. This is not anything new people. Its been around for like 20 years. Dukes been talking about it here for years now. Then Tim, and now me. Nothing new. Do a search - Swarm subwoofer system, Distributed Bass array. Or heck if you're smart do what I did and just go read every single one of Duke's and Tim's posts on the subject.  

What makes this particularly maddening is everything else in audio takes more money than anyone has to do it right. Bass on the other hand, you can have totally awesome and done right for three grand. Easy. Because unlike speakers its not which ones you buy, but how many. Just buy four subs and see.  

The soundstage opens up and becomes enveloping. Why? Because much of our sense of space comes from extreme low frequencies. Waves so long they only have room to run in very large spaces. So when we hear them our brains say hey we're in a large space. Like a concert hall. Totally does the trick.  

Midrange gets clearer, not sure why but probably because now with a proper foundation everything is more in balance. It just sounds right.  

Wake up, people! Wake the you know what up! Or at least, if you are gonna stay asleep, or keep your head buried firmly in the ground, or put your hands over your ears and go NANANANANA I can't hear you! At least if that's the way you're gonna be keep your old going nowhere last millennium fake news to yourself so people have a chance to learn from the few who actually know what they're talking about.

And I for one will be a little less vexed for a change.

What hz ranges are normally sent to a sub?  Do subs generally do an inferior quality vs a high end main?

i like my 12 inch sub for rumbling effects during a movie but as far as quality, my mains may do better.
very very few mains will put out full volume 20 hz bass at the listening position..they are rated -3 db at a few inches away at low volume...I cross my subs over at about 38-40 hz...
