Question about Onkyo TX-NR7100

hello any speaker everything works good day

Hello all I am currently using the Teufel speakers

Passively, anything in the range of 4 - 16 ohms, as well as an active subwoofer. However, I would advise against using a good old Infinity Kappa 8a or 9a, as the receiver will probably not be able to cope with that sooner or later... ;-)
