These things are actually capable of accurate, full range performance with music. If the music was recorded with heavy bass foundation, these play it back like that. I'd go as far as to say that these speakers are actually forgiving in that regard, more than incapable. I know this by listening to the same artists who recorded albums over a period of time, who's bass input changed from album to album, and after being familiar with them with actual full range speakers.
I grew up in the 70's, and spent a great deal of time going to rock concerts, listening to garage/warehouse bands and other outdoor events and mostly because a lot of my friends were/are musicians, some of who are actually still very good. I never recalled anything based below say, the 35hz range, at least not intentionally. It was that mid bass presence that you felt more than anything else.
After doing a great deal of reading on this subject, I am getting the feeling that HT, gaming, bass music and outright generational differences all seemingly being crammed into one package is confusing things quite a bit. When someone claims a certain speaker does not have enough bass, the first thing I am compelled to ask them is how old they are, or when they started seriously listening to music and where. If someone reports that they watch 70% movies, 20% sports and 10% music, I have a hard time with their bass analysis, which is something I have had to watch out for, even with an initial disclaimer saying I primarily listen to music.
I tested these listening to Brian Bromberg playing stand up bass and found out quick like that some of my windows need tightening up and it wasn't turned up very loud. That's pretty much perfect, to my ears at least.
