4 Ohm 20W Resistor Wire Wound

can this resistor be used to convert a 4 ohm speaker ( 20 watts ) to a 8 ohm speaker if placed in series with the speaker ?

Asked by: ire bill
You are correct that the impedance would then be 8 ohms. HOWEVER !!! This technique is never used as the sound quality would suffer immensely. Resistors are not designed for this purpose. Mind you there are very large ones used to load test amps, but this is for testing only - not audio quality. And they are very expensive. So short answer - Don't do it ... hope this helps.
