I vaguely remember that the speaker industry standard rating of impedance as what it is at 1000Hz. Which is kind of silly because the impedance is usually all over the place unless the speakers use series crossovers.
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?
