    Re: How am I supposed to lay all this out?

    Sure. The lines are wires, the dots are connections. Where the lines cross with no dot means no connection. The sawtooths are resistors, the two parallel lines capacitors, and the Hostess Cupcake squiggles are coils. A hot glue gun is nice for gluing components down. The values on the diagram are also on the components. Don't lose the labels off the coils. Good luck.

      This is for the woofer.

        It's not all that hard.
        First crossover I made was from a plan in I think Popular Science magazine.
        I wound my own coils on an engine lathe.
        I had never done anything like that before.
        It worked.

          Pretty sure the upper left coil should be the .22uf cap, but I can't read any component values.

            It is. Both white thingamuhbobbers are 4 ohm resistors, big coil in middle is 1.30mh, 10uf capacitor.

              No, you have an inductor where a capacitor should be. I'm guessing that's your .22mH coil, that instead needs to be a .22 uF cap. Other than that, you have it just right.
              You go your way, I'll go mine. I don't care if we get there on time.

                Okay, I switched it to the small cap.

                  WHAT LOL. I just looked at the schematic and followed it. I'm dumb and put the coil there. I knew something was wrong as other xovers didn't have two coils connecting so close from what I've seen. I'm going to try and get some cardboard the size of the cabinet to fit and play with things.

                    I used a different tweeter as the one he used is NLA. This of course made for crossover changes, if you look at his crossover point of 3100 to 3200 Hz. I have a crossover point of 2000 to 2100 Hz.
                    The sims below are done using in box measurements, so things below 300hz or so is my garage talking back to me or you could say reflections.

                      xsundown, if you are still having a hard time with the layout, please give wolf your board size and let him lay it out for you. If not then you will have to do it like me and keep playing with the alignment until it fits. I wish I would have taken pics of mine for you before giving them away.

                      Wolf hope to see you at MWAF.

                        Mark65 is right about the woofer circuit.

                            I feel something may be wrong but how does this look so far?

                              That woofer circuit is indeed correct. I can't see the values of the top resistor, the coil or the large cap, but the way you have them layed out is correct. Break out the soldering iron.

                                Top left cap is .22uf, top white is 4 ohm 10w 2%, resistor?, black cap is 10uf 250v, coil is 1.3mh 18 gauge, bottom white resistor is 4 ohm 10w 2% same as top white resistor.
