Is there a way to sort of "estimate" an equalization for speakers by doing some audio tests from the speakers with a microphone analysing the frequencies being outputted?

The best way is to use a good measuring microphone and a good real-time equalizer. Check out:

I use the software that comes with my TACT, but there are several PC based options availble. Here is an example of an in-room uncorrected measurement and the post equalization measurement.

^Sounds interesting. Have you got any links to where I can buy that? I'm preferably looking for free software that I can use with any mic. I don't need it to be 100% perfect, just roughly.

I came across this the other day. Looks very good and is free.

Think it would be tricky though to get any improvements more generally than at one point in the room.

Would this software allow me to use any ordinary mic to analyse the frequencies?

No, you are going to need an accurate microphone. The good news is that a pretty accurate one, good enough for this certainly, can be had cheap. The Behringer ECM8000 is a cheap measurement mic with quite a flat frequency response. It'll do the trick nicely and not break the bank.

Do be aware though that equalisation isn't the only problem speakers have, they also distort phase, and equalisers do as well unless they are phase linear (which delay the whole signal). So while you may get a better frequency response, you may end up getting a worse phase curve and not liking the sound as much. Of course this depends on the speakers.
