I'm glad you cleared this up for me, I appreciate it
So, higher impedance means less volume, if you for example use the same amp, same config, but rewire the speakers to series, for whatever reason.
Higher impedance does not damage speakers, only if an amp powerful enough to push more watt through the impedance than the speakers can handle, is connected, and of course, played too loud.
Lower impedance means more power can easier be pushed through the speaker, but hence requires an amp capable of driving at that impedance? (i.e. 4 ohm amp and 2x8 ohm speaker in parallel)
Higher impedance requires you to turn up the volume more to reach same amount of dB as if speakers had lower impedance, and this
also requires a more powerful amp than if the same speakers had been of low impedance.
That being said, it all comes down to the power of the amp, and the speakers can never be damaged if not being over-watted (as in turning up the volume too loud, distortion and blown out drivers).
If I got all that right, then...
What's more damaging for the amp? Too low or too high impedance... I'd say too low, but am I wrong?
Edit: Elaboration... You say if the impedance is doubled the amp delivers half the volume at same setting, so suppose you turn the amp up to the level you want, which would be much louder at lower impedance.
Thanks in advance
