It's about the amp. Amps like to put out at 8 ohms. The mechanical analogy isn't a good one. Instead, think about your past gf's.
Why are low impedance speakers harder to drive than high impedance speakers
I don't understand the electrical reason for this. I look at it from a mechanical point of view. If I have a spring that is of less resistance, and push it with my hand, it takes little effort, and I am not working hard to push it. When I have a stiffer spring (higher resistance) I have to work harder to push it. This is inversely proportional when we are looking at amplifier/speaker values.
So, when I look at a speaker with an 8 ohm rating, it is easier to drive than a speaker with a 4 ohm load. This does not make sense to me, although I know it to be true. I have yet been able to have it explained to me that makes it clear. Can someone explain this to me in a manner that does not require an EE degree?
Thanks
