I'm thinking of building a 3.1 home theater with the B1+ and C1+ speakers. My receiver is a Yamaha RX-V485, but I'm not planning to add more speakers. I know the C1+ is a 4-ohm speaker, and will require more power than the B1+ speakers. I just want to make sure I'm not pushing my receiver to the point where it overheats or breaks down. Will I run into any issues running those speakers on my receiver?
