The Walkthrough - The Crossovers
Above: Yes, they're ugly... but rock-solid!Below: We couldn't really resist a simple test of our circuit... I just hope this didn't cause any damage to the drivers. (We used much nicer wire to connect the drivers once they were within their enclosures.) |

Well, here we are. I suppose you could assemble the crossover networks at any point, but this seemed an appropriate place. Keeping in mind that the crossover is the "heart and soul" of the speaker, we were sure to make superb connections between components at the expense of appearance. If we had more time we could have made them prettier, but nobody is going to look at them... and even so, to most people they look really cool as is. The parts are firmly attached to their bases with a generous helping of hot-glue. If you've never soldered before I suggest you read Wayne's little tutorial. And for those of you who don't know your electical components: the squigly line is an inductor (), the jaggy line is a resistor (), and the parallel lines that have a gap between them are capacitors (). These capacitors are nonpolar, so there's no wrong way to hook them up. Just keep in mind that if ya use a polar capacitor please mind the polarity... or it could explode. Just follow the schematic and all should be well. I happened to be in the odd situation of having in my posession Dayton's new tweeter... but the old crossover diagram. I still need to update my crossovers... but I won't have the time to do that for quite a while. I'm not sure how much of a detriment this is to the sound... I hope not much. The diagram that I have posted on the site is up to spec with the latest Dayton tweeter.
FYI: Wayne assembled the high and low pass segments of the crossovers in two pieces.
Also: Don't forget to attach a few leads on which to attach your drivers later. Additionally, don't forget to drill a few holes of appropriate size on the back pieces where you plan on mounting the binding post terminals.
