Real-time analyzers employing generated pink noise is not as a definitive tool as you might imagine. First, the inexpensive microphone supplied with RTAs do NOT have ruler flat response curves, no microphone does and mic placement is critical as well. Secondly, if you were ever to achieve a ruler flat response from your system as measured and set with your RTA, I believe you would find your musical presentation much too forward, even strident in nature.

Over 20 years in pro sound has taught me that RTAs are useful for getting you into the 'right ballpark' but certainly not the last word in ideal musicality. Our hearing curve is not flat by any means. Our ears evolved over tens of thousands of years to detect best frequencies associated with the human voice. Music reproduction via loudspeakers is a relatively new concept as are loudspeakers that have useable response beyond the limitations of our hearing.

What all this means is you can get close to an ideal response curve with your Behringer but you will need to do a lot of listening to a variety music and some fine tweaking octave by octave to reach your final destination. Musical sounding loudspeakers.

One final word: Straining the electronics (excessive equalization) will lead to an unnatural sound and increased noise and should be avoided. Remember, less of one octave brings about the same result as more of another in the general scheme of things.
Try bringing down the level(s) of the hottest frequencies to meet the frequencies your loudspeakers are not as efficiently reproducing.
