OHM's

[Beginner 1960]

I've saw that it takes twice the power to drive 4ohm speakers than 8ohm is there any other diffriance does one sound better than the other if all things are equall? sorry if its a stupid ? thanks for ur input and help

I'll keep it sweet and simple.

The ohm rating of a speaker is called it's impedance.

The impedance of a speaker is no indicator of how good or bad it sounds.

A speaker rated at a lower impedance will place more "stress" on an amplifier than a speaker of a higher impedance.

The ohm rating of a speaker is an approximation since it varies with the frequency. Generally, the lower the frequency, the more likelyhood of impedance dips. Sometimes, these dips can be significant.

Not stupid at all. This comes up again and again. I will keep this post handy.
