Most of the points made above are valid.
Check the response at the listening position first. @eric_squires had a good suggestion and the 1/3 test tones also.
I used pink noise because it was easy and encompassed the entire spectrum. Flat is flat. unless your measuring instruments roll off or boost frequencies, it is what you are seeing.
If you see any dips (I have a serious dip at 58 hz), or hills, there is your problem.
Is it a particular component in your system? Speakers, source, pre-amp, amp? or the room? But, doing this test, at least you can see if there is a problem.
If it shows too much bass because you have three million REL subwoofers, but you like how it sounds, then more power to you.
I want my system and room to give me as close to a flat response as possible. That is how equipment is typically designed, unless the manufacturer is playing games.
Flat first, then adjust as you like.
Heck, I've gone to some serious hi end dealers and listened to their top equipment and they were sitting there trying to sell my friends and I on how much bass response the speakers had. "you can feel it in your chest" they would say. And I, who played classical violin, sax, etc. would say, you know that is way too much bass.
This is very similar to younger people who are used to MP3 or compressed digital and think this is great. it is all they ever heard and people told them it was good. Too much bass is too much bass. was it really recorded that way?
Anyway, just my thoughts.
