Why do so many people have problems with bass?

@engineears while I agree with some of what you say, I disagree in principle and fact with a lot of it.

Bass nodes, the high and low peak are totally predictable. There are even simple tools on the web to help. Those nodes are always a function of the distance of walls from each other. How deep those hills and valleys are is impacted by speaker position. This is also fairly simple to understand, predictable, and again there are simple tools to help understand.

You also ignore some simple rules and simple solutions. A simple rule and solution is never use one sub. Always use two of more. More subs in the right spots, smaller hills and valleys. Simple rule, if your main speakers are in bad spots for bass out of necessity, then don't let them play that bass if you have that option. Let the subs do all the bass work. Your mains may be happier as well. Simple solutions, you can buy subs with room correction built in. You can also use external devices to control this.

@asvjerry - Deep bass in that song, but not really deep. Bass guitar does not have much below 40Hz, and very little below 35Hz. You were not wrong @daledeee1. Piano can go lower, but not used much, and electronic music can. Some orchestra instruments can but will not account for much of the music.

I learned to love my Bass listening to Lesh and the Dead In the 70's live- I saw the "Wall of Sound" maybe 10 times and you could hear a drumstick break 50 yards away. The watts was  like 50, 000 and the system itself was famously built in the first place because the Bass needed a 40' standing wave to operate properly. For home use after owning many homes and many systems of only moderate means (SoCal); I could never get the real Bass I wanted to deliver and finally just sort of gave up. I Use a couple of Harbeth 30.1's now and I always must remind myself not to go get some Subwoofers- Tho I shop.

I've never had a problem getting low bass in my mid sized apt living room. Right now I'm using JBL 4319 monitors and with it's 12" bass driver, things rattle in my room. I even got some rattling (but not as much) with an older pair of Clearwave Duet monitors with just a 6" mid bass driver.

I don't understand everyone's dilemma, unless it's unnatural bass they're after. Those 12" drivers on my JBLs roll off below 40Hz and with proper playback, it's super tight, defined, textured as all get out and thumping when needed.

I'd look at one's set up further up the chain from the speakers if I'm having problems with bass response, unless the problem really is in the speaker design, in which case, you'll need better made speakers.

All the best,

Fascinating responses.

When I was shopping for speakers recently it was very clear the driver sizes for bass are getting smaller. The reason I was given is that most people like the smaller speakers, smaller more narrow speakers that they contend look nicer and wanted by consumers.. No matter how much I wanted to spend on speakers it was challenging to find larger driver size unless I really stretch higher.  My older speakers have 8 inch drivers which r a nice size for bass. To get these in a current speaker is extremely expensive because they don’t design speakers that way anymore.

It’s no wonder people aren’t happy with the sound. Personally I think all the challenging lower frequency areas touted as being a challenge to deal with is a lot of bs. Filling a room with lower frequency base should not be a big deal.

Physics and Driver size go together. You need wider main speakers with a decent sized bass driver or two along with a decent amplifier and problem solved, you have bass. You are a genius.

Current speaker designs with smaller driver sizes, and all the marketing and confusion are leading Music listeners Down a path filled with modern age deficient speakers and deception to sell more stuff.

In a room?
