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
