Seeking "Crossover Networks For Dummies," please


Hello, Gang,
I would very much like to read a thread which is a kind of primer on speaker crossover networks. I do understand that this topic encompasses a lot of complicated material, including electronics and physics!
Still, I'd like to know more about this topic. It would help me to understand some of the opinions and controversies I've read here over the years.
What factors or "philosophy" might cause the designer to choose, say, a second order network over a first order network? I've seen people on this forum post things like, "I cannot listen to anything other than a totally time coherent and phase coherent, first order network." On the other hand, there are much loved and highly regarded speakers out there that use second order and fourth-order networks!
Anyway, I'd love to understand more about this topic.
Thanks!

The Linkwitz (might be Orion speakers - check the A'gon Industry Directory to be sure) web site has some really good info on the subject and touches directly on the questions you pose.

Drew,

"monotonically increasing directivity index"?

I assume that directivity increases with frequency, but I am unsure what is meant by "monotonic" in this context. Can you shed some light?

Thanks,

Marty
