What Mapman said. he nails it.

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 |
