I purchased these speakers a few months ago, and they have not ceased to amaze me. They almost don't need a subwoofer. Infact, once I calibrated them using a complex graphical analysis of their frequency response, the bass response and overall neutrality of the speaker improved dramatically. Of course, EQing the bass up a tad lowers the safe max output of the speaker, but since I use them as desktop / computer speakers, I don't need anything past moderate volume levels anyway.
I use a program called AIMP3 to play music. It is designed specifically for audiophiles / professionals, and includes innumerable advanced features, including an 18-band graphical EQ accurate to 0.3 dB. After the calibration mentioned above (and before accounting for room modes / speaker placement), these are the EQ settings I use:
31hz(-0.3), 63hz(-1.8), 87hz(-2.7), 125hz(-4.2), 175hz(-4.8), 250hz(-2.4), 350hz(-2.4), 500hz(-1.2), 700hz(-3), 1Khz(-4.8), 1.4khz(-2.4), 2khz(-4.5), 2.8khz(-4.8), 4khz(-3), 5.6khz(-3.9), 8khz(-1.8), 11.2khz(-5.1), 16khz(-6.3)
I hope this becomes of use to others.
