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.
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!
I don't think the OP has any REAL intentions about the improvement of his current system or maybe is curious?. This post is obviously a post to invite a FLOOD of responses to address the issue "with bass".
If you really want to find about "bass" the best way is to get the opinions of everyone you know, and the rest of Earth's population.
Three possible problems with bass.
1. Room nodes mainly based on speaker location and room dimensions. There are zero nodes and big bass nodes and you need to place the listening seat and speaker location to minimize these affects.
2. Speaker bass design. Most speakers(without subs) start rolling off above 40 Hz. And many speakers have bass overhang, especially in the mid bass where the bass is sloppy. This is from speaker design. Some times it's even deliberate on the designer since heavy bass even when sloppy sells. I'll add, when designed properly closed boxes(very rare these days) are cleaner than ported boxes and this is inherent in the two topologies.
3. Fletcher/Munsen. Frequency response of our ears rolls off at bass and treble frequencies. If I recall bass is flat at 100dB(way too loud and dangerous to hearing) So even at normal loud levels the bass may be there but sounding reduced even when it's not due to the nature of the way our hearing works.
