A:Answer Hi Jay,
When matching speakers and Audio/Video (A/V) receivers, the ohm rating of the speaker should be equal to or greater than the ohm rating of the receiver to avoid a risk of hardware damage.
Any speakers that feature bare wire connection will work to this receiver, as long as their impedances are from 6 to 16 ohms. More details:
