Sansui 8080 with AR-91 speakers?

[gcrimmins]

I recently bought a Sansui 890 receiver, which is apparently an 8080 with a black faceplate. It's an 80wpc receiver, so it should have plenty of power for the AR-91's. Above the speaker connectors it just says, "8 Ohms," so I'm wondering if it can handle the 4-ohm load of the AR-91's. Thanks,
