4 channel surround sound with dsp speakers.

[prateekatasniya]

My uncle has genelec 8341 pair and 7360b subwoofer.
He wants to add 2 rear surround speakers.
As these speakers have built in DAC he wishes to connect the speakers digitally.
Is there any option to connect 4.1 digitally for surround sound?
Budget is around 1 lakh.

Thanks
