Let me ask another question:
So, does a 4-ohm speaker play louder than an 8-ohm speaker with the same amplifier and volume setting?

What does Nominal Impedance mean?
What does Nominal Impedance mean?
I’m trying to decide on some new speakers (Clarisys Minute). They are rated at 86-88 sensitivity and a nominal impedance of 3.5 flat. Although graphs show it about 6 ohms from 20hz-500hz and at 2Khz and above about 3 ohms.
My present speakers, Focal Sopra 2 are rated as 91 sensitivity and 8-ohm nominal impedance, but minimum is 3 ohms.
So, I am presently using Bob Carver 350 amps (rated as 350 Amps/channel 8 ohm and 400 watts /channel 4 ohm) which are tube mono blocks. and I like to crank it up at times!
Can someone explain about Nominal Impedance and if my amp(s) will have a problem driving the Clarisys Minute speakers?

no, depends on speaker sensitivity and more broadly, i believe nominal impedance is basically a useless measure speaker makers don't use the same standards and pretty much write anything into their marketing literature - always always looks at the whole impedance curve |

As I understand, only in 8 Ohm load does 2.83 volts produce 1 watt. In a 4 Ohm load 2.83 volts produces 2 watts. 😎 Mike |
