Right. Only its not exactly like you will feel its still needed. More like when you add it you will be surprised and wish you'd done it sooner.
Its hard to explain but I think it has to do with the way really low bass works. With moderately low bass, like 30-40 there are lots of times where its pretty easy to spot. You hear a bass line, get the feeling that as the notes go lower they should be all the same, but they're not. They trail off. So you know to do something about that.
Really low bass though is completely different. Its not even hardly heard at all. Its more a sensation. And its there in some surprising ways and sometimes where you would never expect it. A lot of the time its not even really part of the music. Its more a part of the room. In other words a big recording room or concert hall, it has a natural reverb to it that is very low depending on its size. You don't really hear this, but you do feel it. Sense it. This is what people mean when they say good bass opens up the sound stage. Its really opening up your room by making it feel not like the little room that it is but the big one the music was in. We're used to that from good imaging where the high frequencies seem to make the stage extend out beyond the walls. But with really low bass its not just in front on the stage. You are enveloped in it.
