So, I have a 2.1 system that sounds pretty ok, but yesterday I was running a test (https://m.youtube.com/watch?v=AC-ExFnAgXo&pp=ygUMc3BlYWtlciB0ZXN0) that revealed that I have some wild volume differences between certain frequencies all over the spectrum. I then listened to the same thing over my headphones (Beyerdynamic DT770 Pro) and there all frequencies had pretty much the same volume.
Is this normal or should I aim for equal volume over all frequencies for my stereo? If so, what’s the best way of attack? Room treatment?
Most speakers don’t have flat response and even when they do that is in near perfect conditions which your room is almost certainly not. Room treatment could improve things for you greatly.
