digital crossover and equalizer hifi setup

[Heiko Kokemoor]

Hi,

I want to to use a PC as a part of my hifi-equipment.

 2-way crossover and equalizer

My goal is to fully activate my open buffle loudspeakers, the equalizer
is needed for the subwoofer.

Could this job be done with Ubuntu Studio in a, hm, easy way?
I have read about brutefir, but I have problems with routing etc.

I don't expect an easy how-to (even I would like to have :-)), more a
hint, which software I should take some looks on.

regards
