"Perfect" equalizer settings Options

[mipadi]

I've been trying to adjust my EQ settings in iTunes in order to get decent output on my MacBook Pro's relatively small speakers. Prior to this I owned an iBook, and for the last several years I've been using an EQ setting (dubbed "Perfect" by its creator) that looks like this:

The sound output is okay, I guess, but when I really thought about it tonight, it seems like its all wrong. Adjusting the EQ revolves around a few premises:

1. Music is recorded, mixed, and mastered on speakers that give a flat frequency response;
2. Ideally, all speakers have a flat frequency response;
3. But this is not the case, so EQ settings attempt to overcome the imperfections of a particular speaker setup so it seems to give a flat frequency response.

Given that, it seems these EQ settings are all wrong. They boost the bass, which is probably okay, but they lower the mids (which are probably muddled to begin with), and they really jack up the highs, which doesn't make a lot of sense on small speakers.

So I'm looking for tips on how to properly adjust the EQ. I know, I know -- why don't I just, um, listen to the f*cking music and adjust the EQ until it sounds good, right? But now I'm all psyched out that I've been listening to music on a laptop with a f*cked-up EQ setting, and I don't even know how it should really sound anymore.

Can anyone give any tips for adjusting EQ settings for small laptop speakers (particularly those on the MacBook Pro), or (perhaps better yet) articles or pointers on adjusting the EQ myself? And maybe some tips for adjusting the EQ to sound good on headphones, as well?
