Using Ohms law (1) we can calculate the following relationships: Equivalent Impedance also known as the Thevenin Impedance where we short our voltage source (in this case our amplifier) to calculate ...

BR><BR>Putting them in parallel won't work - 2 6 ohm speakers in parallel will work as one 3 ohm, and I have the receiver set to 6 ohms. The remaining option then is to put them in series.

BR><BR>I have narrowed it down to 2 models from the same manufacturer and series of speakers.<BR><BR>Option ... Amp. Power, 8 Ohm 30 - 150 Watts <BR>High Frequency Driver 1" <BR>Low Frequency ...

Depending on the design of the speaker, the impedance at any frequency could vary between 2 and 8 ohms, or even go as high as 40 ohms! This rating is almost always an average. This "nominal" range ...
