This is just a hypithetical question concerning a speakers rated "nominal impedance".

Without getting into any scientific discussion, lets say you had a fairly good quality 2 channel audio amp rated at 100 w/ch continuous ... Your hooking this amp up to power (4) intentical floor standing speakers, each rated to accept between 20w minimum and a max recommened power of 120w.

Lets say you have 2 different sets of (4) speakers each. Remember, we want to power 4 speakers (front and rear) with this 2 channel amp ... Both sets of speakers are basically the same and have the same sensitivity rating ... Now, for the questions:

1. If one set of these speaker sets were 8 Ohm and the other set was rated at 6 Ohm ... would the amp have a harder time driving the 6 Ohm speakers when pushed for loud listening levels vs the 8 Ohm speakers?

2. Would the 6 Ohm speakers be louder than the 8 Ohm speakers when the volume knob on the amp is set at the same place?

3. Again, if you planned on using 4 of the same floor standing speakers in your 2 channel audio system, and the 2 sets of speakers you were to choose from were basically identical except for there Ohm rating ... Generally speaking, would you choose the ones rated as 8 Ohms or the speakers rated as 6 Ohms for day to day listening at moderate listening levels if eveything thing else was the same?

Thank's for any input
