Flat impedance curve?


Hi,

How big impedance intervals can speakers have and still be considered as "flat"? I have a pair of 4 ohm speakers (Isophon Galileo) that has a maximum impedance of 10 ohm at a certain frequency and dips to 2 ohm at another. Are these speakers flat?

Can I use these speakers together with an 4 ohm tube amp or is that not a wise choice?

You might find it that it might be a bit more complicated than that. It might be more beneficial to see a graph of the impedance, to see how and where the impedance varies. The phase angle can be just as important in considering amps for speakers. IMHO, what your proposing doesn't appear to be ideal.
