I'll try with a commonly used analogy that might just work in this example.Ha, this is something new I’m learning. I thought it was because, at some point, the amp could no longer produce enough power to drive the speakers as the resistance dropped. But you said that the lower the resistance, the easier it is for the amp, which makes sense to me. But now, with the current coming into play, I’m even more confused.
If impedance decreases, more current will flow -assuming the power source can handle it. Otherwise, the voltage may drop.
Look at voltage like water pressure in a hose, while current represents the flow of water.
If you start with a pressure of 10 (arbitrary) and make a small hole in the hose with a nail, a small stream of water escapes, but the pressure remains close to 10 because the source can keep up. However, if you cut off the end of the hose, a large amount of water rushes out. If the pump has a limited capacity, it won’t be able to maintain the pressure, which may drop to 2. Similarly, in an electrical circuit, if impedance drops too low, the power supply might struggle to provide enough current, leading to a voltage drop.
When this happens, you risk distortion or clipping.
