Dali Spector 6


Hello,i read so much that i am very confused!I have an amp,Marantz SR 4021 and i would like to put Dali spector 6 on it!
Dali specs are 30 - 150 Watt at 6 ohmThe official amp site says 2x80W at 8 ohms  and 2x100W at 6 ohms,but in the back of the amp i saw this :

SYSTEM 1: 4-16 OHMS
SYSTEM 2: 4-16 OHMS
SYSTEM 1+2: 8-16 OHMS
So i am not sure!Is this going to cause me problems at the speakers or the amp?

Thank you
