It probably would work, but the sonos only puts out 50watts rated at 8ohms, so at low to moderate listening levels it might work. The 80's are 4ohm speakers and most people drive them with powerful AVR's or receivers. If your going to pay that much for audiophile speakers, you might want to invest in a receiver that will do the 80's justice. This is just my opinion. You would be better off getting some decent bookshelf speakers like the m3's or m22's possibly. Again 50watts for a sonos would be different than a Harman Kardon receiver rated at the same power.
