Crossovers


Okay, I'm confused about the various types of crossovers. From first order to fourth order Linkwitz-Riley, there's a ton of various setups and schools of thought. What's the difference? What do the "orders" mean? I've tried looking around online, but most of the explanations are very technical. While I'm not a complete lunkhead about this stuff, what I'm really looking for is an explanation that can be understood without a degree in electrical engineering or decades of speaker-building experience.

If anyone would like to attempt a layman's explanation of the theory and application, I'm interested.

Indeed, it depends...on LOTS of things. BUT...I believe you should not obsess about crossover networks or even make the simplicity/complexity of the crossover a 2nd or 3rd priority. LISTEN to them and go for the best-sounding speaker system you can afford.

You certainly have some overall considerations. Perhaps you're like my friend, a 'worn-out diddeebopper', who values grace under (high sound) pressure above all. He simply walks away from systems, no matter HOW else they sound, if they don't sound at ease while driven VERY LOUDLY*. Or perhaps you value razor-sharp imaging? Or perhaps you value overall soundstaging...ie the mimicking of the concert hall...above all else.

AFTER you buy a speaker, live with it for a while. If you still love it after 6 months or a year, consider improving the crossover components. But first, fall in love with a speaker.

OK, good.

Generally, high-order filters are used to increase power handling at the expense of phase coherency.
