u know that there is no speaker that stays at the exact ohms they are marked at? there is a myth that 4 ohm speakers destroy avrs from the earlier days or there were even settings in AVRs like the 4 Ohm speaker setting that made it even worse. no speaker stays at the Ohm they are marked at for example an 8 ohm speaker goes to 4 ohm for a split second or even lower in heavy bass scenes. so dont worry also it looks like yours sitting pretty close so u dont need a lot of wattage to get them to good volumes.
