Can I control 8+ audio channels?

Hi,

For a special setup I would like to play sound to 8 channels, plus possibly a subwoofer.
The 8 speakers will be placed inside all corners of a cube surrounding the listener.
So we have:
left-front-upper
right-front-upper
left-front-lower
right-front-lower
left-back-upper
right-back-upper
left-back-lower
right-back-lower

Can I somehow control this with Unity?

Can I for instance setup a (mono) listener for each speaker.
Or can I place two 3D listeners (one upper and one lower listener), each for 4 speakers, to make this work?
Can I route different listeners to different sound card channels?

I hope someone can advise me on this.
