    Default Should I switch to 4ohms????

    I have the Mirage OS3 series speakers(miragespeakers.com) which can do 4ohms minimum and 8ohms, my yamaha receiver seems to do more watts per channel in 4ohms than 8ohms, should i switch to 4ohms or just leave it at 8ohms?

    As the speaker dips, the amp will output more. Many times if you put an AVR in 4ohm mode, like Onkyo, it actually limits power to protect the AVR. Im not sure how the Yammie works though.

    A lot of folks with Onkyo's leave them in 6ohm+ mode even when running 4ohm speakers simply for that reason.

    Speaker impedance actually varies with frequency, so the impedance spec is just an approximation. Some manufacturers also tell you the lowest impedance the speaker reaches over the audio frequency range. An amplifier will deliver more power into a lower impedance than into a higher one (because the lower impedance draws greater current for a given voltage output). But when a receiver has an 8-ohm/4-ohm switch, the purpose of the 4-ohm setting is to protect the receiver's output stage from damage that could be caused by excessive current flow. They almost always work by lowering the receiver's maximum voltage output in the 4-ohm setting, which in turn reduces the maximum power it can deliver. Unless your speakers' rated nominal (not minimum) impedance is 4 ohms, or you're having problems with the receiver shutting itself down, you'll get maximum performance with the 8-ohm setting.
