seeing a frequency response curve on a screen is not going to improve a sound to your liking, only your ears can, if it seems lacking in a certain range eq it to your satisfaction. people perceive sound differently. prior illnesses, congenital defects and general ear hygene can make things sound wildly different for different people. some people who have had tubes put in their ears, or had a burst eardrum will hear things differently due to scar tissue.. As my sound is kind of warm and I'd like to see it in an RTA to see how I could improve my sound to my likings, instead of just doing it all by ear.
