Thanks , Jim D

You only get max power transfer if you match the speaker impedances
exactly.
If you use a lower speaker impedance than the source you can overload
the amplifier and damage it.
If you use a higher impedance speaker than source you will not damage
anything but you will get some reduction in maximum volume obtainable.
