    I see in his photos that where he's lining up the inductor leads, it's already scraped/tinned. However, that's a really good point, just in case he decides to trim the inductor leads. Good one Ron.

      Don't get discouraged! You are doing fine! If this is because of my suggestion on how to condense the board, I wasn't saying your layout is wrong, I was only trying to give advice on how to make the board smaller.

        Oh no. It's because I thought I had everything but forgot those terminals. Just another day wasted by my noobness. :D I just need some sleep. Been at this all day. My head is full of coils and cardboard right now lol.

          Just to be clear you don't NEED those terminals. They just make things a bit easier IMO. You could use wire nuts if you want, or you could solder everything to each point, including the drivers and the terminal cups. It's up to you. Here's the rub. If you make a mistake and you've soldered everything, it's much harder to desolder and correct the mistake....that's all. Thinking proactively on your behalf.

            They're neat, but you don't have to have them. I used them on my first xo, then never again, because by the time I get around to building the xo I've lost all patience and just solder it all together on top of the board. I have pretty much given up on neat,I just want them to work. I do make them small, though, so they'll fit easier, because I have been doing pretty small boxes.
            You go your way, I'll go mine. I don't care if we get there on time.

                Dont let all these perfectionists with their pretty crossovers get you confused, no one is going to see the inside of your speaker. All that matters is that the layout is correct.

                  Then the slot is (0.5" x 6.5") x 9.5" deep, according to your estimates. It's only 13:1.

                  FWIW- I don't think I would sweat it. Sounds like a decent idea to me.

                    IMO, I think this LCR will provide a dip between about 8 and 12kHz, and go back up to 20k; as far as transfer functions go. The CR 'zobel' is to tilt down the very topend, and the 40uF is for level.
                    This is to address a peak in the passband, and then a dip that rises above the bump. I don't recall what the Silkie looks like up there, but the measurements show peeps did his homework.

Am I doing something wrong here?

                      I just finished an active 2 way using the DC28F-8 and a miniDSP. This tweeter has a peak around 16k that even my old ears can hear because it brings up the 12k to 15k. Once tamed, they sound good. I wound up using -4db at 16.5 kHz (Q=3). L2 C5 R3 looks like about -5dB at 15.9kHz. I would say that looks about right.

                        I have the terminals now and have no idea where to put them.

                          Nevermind, looks like I'm pising people off with the questions since someone changed the title. Bye.

                            No, no. Come back. Everything is cool. We want to help you get started. We will get you through this.

                            I misinterpreted the title the same as you. I went back and now I understand the title change. Chris Roemer was not saying stop asking for help. He wanted you to hold on for a minute, while he asked for help from the original crossover designer. I didn't notice the title change when I posted a reply, or I would have changed it back.

                              It's impossible getting all this crap on this little board. I have to bridge grounds from one corner to the other, same for positive. I'm done.
