My I suggest the possibility that you are looking at the wrong tools for your problem? I think you are not looking for an equalizer. You are looking for digital room correction (aka DRC) fitting your speakers with their characteristics into your room with its characteristics and make it sound right[TM] and without any quirky "characteristics". The tools for this (as far as I remember, its been a while since I set mine up): - aliki to record the impulse-response of your setup - drc to compute the correction impulse to be folded onto your signal - jconvolver to actually fold your music signal with the correction pulse. This will be your work-horse. - And of course jack to plug it all toghether. The first two steps would be done on your main machine (but playing the measurement-sweeps through your actual speakers). jack and jconvolver would run on your headless music server. The results are far better then anything you can achieve with an EQ, regardless how many bands it might have. An EQ can never compensate for the time-effects of your setup. Have fun, Arnold
