I want to purchase the Yamaha RX-V677 av receiver but I don't know much about speaker impedance and frequency settings. I wanted to know if these Wharfedale speakers are compatible with the Yamaha RX-V677. I'll list down the specs for the receiver and speakers so you guys can know if they're compatible or not. I would be grateful If you could also point out if the Wharfedale Vardus VR-400 is compatible with the receiver or not.
