In order to find your response curve and try to equalize it out, you'd need to get an SPL meter and graph it yourself using test tones or you could get an professional mic and a program to do it.
I wouldn't bother with inexpensive speakers like these. I didn't even mess with anything like that. I just used my SPL meter to calibrate my speakers to the same volume at the listening position and set the gain on my sub so it integrates well with the speakers.
As for the equalizer, not all cards will have that. My Santa Cruz had one and my HDA X-Mystique has one, but my Chaintech AV-710 didn't.
I think most music players on your computer would have one that you can mess around with.
If you're really serious about getting everything calibrated right, a software equalizer could help you out a bit. You'll still need a mic and program or SPL meter to check the volume at different tones. It's very hard to tell by ear the relative volume of tones at different frequencies and our ears are not as sensitive through the whole range.
So does the nvidia nforce 2 sound card have a equalizer? And is a mic a microphone? What do I do with a microphone and a program? and does flat response really mean accruate? What if the composer or musician intended for the bass to be loud and the violin to be soft?
