Question about crossovers.

I know that crossovers are developed for the specific loads that will be presented to them. I don't know how load affects them though. Can someone explain to me in a generice way?

Take this for instance. I have a 2 way crossover made for 4 ohm components. The point for high pass and low pass is 4300hz at a slope of 12db. Now how would the frequency and slope be affected by using an 8ohm woofer and tweeter?

The xover point would double...making it 8600hz. You can now see why this is a bad thing and affects performance //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Likewise, if you had an xover with a point of 4.3khz and was designed for 8ohm speakers, using it with 4ohm speakers would result in the xover points would be halved (making it 2.15khz)

Thanks for the reply squeak. That really is a big diference.
