Have you ever wondered how the tweeter and woofer have their responses combined in a speaker system, or what the crossover network is and how it works? This article sheds some light on the least seen and perhaps most undervalued part of the speaker system, the crossover network. While passive crossover components and materials and construction have changed over time, the underlying theory and practice has not. In the real world, capacitors, inductors and resistors exhibit behavior which is neither ideal or perfect. In this article, we considered the importance of real loudspeaker impedance, and how it acts as a monkey wrench to complicate and frustrate the function of constant resistance type crossover networks.

Nice article Gene
I still think the Emotiva ERT-8.3 crossover was designed by somebody who's a little anal.
Everything is perfectly lined up.

It's interesting to me the apparent quality of the crossover in the ERM speakers that Emotiva is producing. I noticed a huge difference between the crossover build quality comparing my CSi30 vs. the ERM-6.2 monitor. While the "claimed" low freq response of the CSi30 is lower than the ERM-6.2, it seems that the ERM actually goes deeper to me even though it begins rolling off at 80 Hz. It also considerably has better dispersion IMO. Does the crossover affect the SQ that much? I know driver design also plays a large role here too.
Some people go so far to say that when you listen to a speaker, you are really listening to the crossover. I think they're implying that the greatest variations (and/or chances to screw up) are here.
So, yes, crossover design and execution is going to make a difference.
Curiously, the crossover pictured by MajorLoser appears to use iron core inductors, which are the worst component you can build with if they are in series with the driver. I don't think it matters as much if they are used as shunts.
These are some of the components used in my crossovers would you say they are pretty decend?
State of the art premium internal components include Mundorf Supreme™ silver oil capacitors, HQ Jantzen ™ air core inductors, interior resonance suppressant coatings, and proprietary multi-composite main assembly. Ideal for Home Theater or Stereo it is especially well suited for large rooms
