Why do so many people have problems with bass?

@jumia , I will give you a hint. Stand in the middle of your room. Look around. You can probably see the problem source. Most people have 6 of them. Some have more. Large flat surface. They reflect. Your room is like a giant bath tub for bass. Slosh the water in the bathtub just the right speed and you can make a mess pretty easy. That is the main problem. Most audiophile have speakers that can put out enough bass for most music. Maybe not for movies, but for music, sure. But it goes everywhere, and just like that bathtub, it sloshes around, and you get high and low points, and because your 6 flat surfaces are all different distances from each other, the peaks and troughs are not all in the same spots. You can move your speakers and make it better, but never perfect. To do that costs money. More speakers or lots of things to absorb sound and bass takes a lot of space and mass to absorb. Audiophiles also seem obsessed with a single set of big speakers. If you happen to get two big speakers in the perfect spot for perfect bass and perfect everything else, go buy a lottery ticket or apply for your Nobel. If you can afford the room and pissing off your soon to be ex with enough things to tame the bass from two big full range, sure go for it. If you can't, and your want good bass, there are better ways.

I wouldn't know what to say, that seems like a really good question though.

Well, it's a huge part of a truly high fidelity system. The details are really beyond the scope of what what can be said on a forum of this nature but for me besides my background in physics, educating myself about acoustics and using a good testing rig like REW laptop software and berringer mic. has helped me to arrive at a really good solution. Active analog crossover and dedicated mono amplifier is key for me as well.

As I type I sit in front of a giant with 4x21" woofers 

I can't imagine how gawdawful that must sound.

IMO, the early 80's started the trend which pointed out that most of the music is in the midrange.. The response, was an effort to clean up and boost the clarity, They would cut the bass response. And they cut it too much IMO. Yes, the music was clean and maybe even accurate. But it was DEAD. It had no life. It laid flat. At least in the R&R genre.

I suspect the R&R’ers may have heard it before the majority because bass is nearly impossible to do without a GOOD bass line and drums (rythem section) Then too, It took some time after that bass reduction beforet a solution was offered. It was a sub woofer. Now you can have the bass back...but ya gotta pay! 
At the time in the 80's I believed it was a cost cutting measure since Bass costs more to reproduce. So the clean mids fit the audiophile desire , while the sub was a winner to the marketers. because It equaled extra $$$. The speakers didn’t go down in price. Instead, they went up in price and were sold as “clean & accurate sound ” in the same manner that lack of chrome on  cars in the later 60's,   was sold as “Streamlining” Its just modern marketing. Creating new markets.
