I read a flat impedance curve is better for the amp.
So I got the Fane Sovereign 12-250TC.
It has the following impedance curve:
I want this curve to be flat.
After some research I found out I can tame the upper end using a zobel circuit.
But...
what can be done about the lower end (at Fs) of the curve?
Are there any disadvantages to this approach?

An externally hosted image should be here but it was not working when we last tested it.
An amplifier with low output impedance will largely be unaffected by changes in the impedance of the loudspeaker.
As the output impedance rises you need to start paying attention to speaker impedance. If you have a current amplifer (output impedance >> speaker impedance) you want to have a very flat impedance curve.

OK.
I think I get it.
Let`s say I got a 4 ohms amp.
Now I take a few speakers wire them parallel to around 2 ohms.
And connect them to the amp.
It is not ideal and of course I won't run it full blast.
In this scenario it will make a difference if speaker impedance is compensated.
But a 4 ohms speaker on a 4 ohms amp,
and a 8 ohms speaker on a 4 ohms amp for example is negligible.
