hello folk's...

i've a 10.1 sorround receiver and i can controle the volume of each speaker.
But i want to control how it sounds from each speaker in my living room.
Because i have 7 small (inkl. center), one subwoofer and two big front speakers,
i want to control how much bass and treble they give...
Does someone know such a program, it would be a great help...

Thank you...
