I think that Dragon has a pretty good point here. I replied to a post by I think Fishmed one time about using EQ to the monitors. The problem is that your signal is going to get phase shifted. Adding any filter to an audio signal will do this. That is why there is so much emphasis on getting the kind of sound you want going to tape. Having to add EQ to anything is going to have some drawbacks. You also have to consider the quality of any EQ that you apply. I am sorry to say, but if you didn't pay a small fortune for that EQ, whether it be digital, or analog, it is not going to be THAT great.
The next thing that is important to address here with your monitors is the signal path. If ANYTHING in your monitor signal path is bad, your mixes will reflect this. Even in the case that you are listening to alot of pro mixes through it. Bottom line here, buy some Monster Studio Link 1000 audio and speaker cable for your monitor path. I can't even begin to tell you the difference in the quality of the sound when you use this wire. You can start hearing things that you couldn't before. Next, you gotta have an amp that rocks! I have a Hafler P-3000. This amp is like minimum studio grade stuff. I have listened to my same monitors through other amps and could really tell the difference. But at about $700-800, this amp is not for the financially challenged.
Now, if you are having trouble hearing the high's and low's through Event 20/20's, time for a good old hearing check S8-N. I think that in your fall from grace with the big guy upstairs, he might have planted a few bugs genetically in you......
(all in fun here). But to be serious, I really would pay very close attention to how loud you are monitoring.
What I have found is that when I need to monitor for very long periods of time, if I have them up too loud, I tend to start doing some very funky things with the EQ on induvidual tracks. This is not a good thing. I have to constantly remind myself to keep things quiet on those long mixes. Especially in the case that clients pay me to hear things that they don't, I can't afford to suffer from ear fatigue.
Also, low end build up has to be the number one offender in a control room. Your room needs to solve a lot of problems with phase cancellation and what not for you to start getting accurate low end. Resonating walls, phase cancellation, reverberation times, etc...in the room will have a dramatic effect on how you hear things. This includes pro music you listen to through your system.
Now, about the low's and high's, as an engineer, you have to think in terms of what is good for the music, more than your own preferences. I really dig that "scooped" out sound myself, but it is not the way to actually conduct a mix, unless I know for a fact that the person that will be listening to the product will have a similar system and room to mine, and also has the same taste in EQ. The idea in mixing is to give the listener a well balanced mix sonically speaking. Too much emphasis in any realm will not give the end user the chance to adjust to THEIR preferences, which could really differ from yours. This is the reality of engineering. You can't really have it the way you want if you are trying to make money off of it. You gotta strive to deliver a versatile product that allows the buyer some options so to speak. Also in the digital realm, low end is deeper, and reproduced much better than analog. And with issues concerning bit resolution, the high end really needs some attention and some presence when working with digital because of digitals funkyness in the high end that is inherent. By chewing up meters with low end, you don't really have much room for the frequencies that need all the help it can get.
Anyway, I am starting an essay here, and this is the wrong place for that. The Events do tend to be a bit weird in the low end, but also work with low end much better than many other monitors. Just listen to a lot of stuff and try to emulate what sounds good to you if it is appropriate.
Good luck.

These things only cost about $40, BTW.
It's a cruel loop.
