Very nice tutorial. I follow pretty much the same procedure, but never use the screw terminals. I just solder some wires directly to it. The rubber gaskets is a nice tip. Until now I just screwed them to the inside of the box with some 5mm long M4 nylon washers in between. Never had any issue with rattles, but your method does make sense to me.

I'm totally confused! Do you have any idea how he translated the technical circuit drawing at 4:22 into the reality he laid out at 8:36? Is there a code for translating one to the other? They look nothing like each other.

@olobiksnagol2178 3 жыл бұрын

@@greenbeginner9221 The diagram at 4:22 represents the desired circuit, at 8:36 he's showing the practical application. Often when I'm designing a circuit of any kind I'll draw it out (CAD or paper & pen) so I understand which components I need and how they're connected. When I go to implement a circuit the space available dictates how the circuit will be manipulated to fit, but the original drawing still dictates the connections which I must make. I will also breadboard circuits using multiple breadboards to test them before implementing. If this doesn't help please reply with details which are not clear.

@@olobiksnagol2178 Here's my chief point of confusion: You say that you use the schematic to determine how the components are to be connected. That's what I'm missing. How do I determine those connections? Here's an example schematic: It's the first image called Crowbar Circuit www.allaboutcircuits.com/technical-articles/understanding-schematics/ There's a horizontal wire running across the bottom from 0V on the left and Load on the right. There are four dots on this wire. So, that tells my mind that I use a razor blade and expose the metal of that wire in four places so that four vertical wires can be soldered in those four locations and the order of events is maintained. But maybe there is no order of events. If that is so, I can skip a lot of the wire stripping and connect the ends of all four vertical wires In a single junction along with the point called 0V and the point called Load. Which one is correct or am I totally misunderstanding?

@olobiksnagol2178 3 жыл бұрын

@@greenbeginner9221 The order of events should be maintained, your example," Crowbar Circuit" is pretty straight forward. You could indeed use a razor, strip the wire at the points indicated, and solder the components in the order shown, and the circuit would function as designed. Connecting all of the components to two junction points OV and Load would result in a circuit that will not provide the expected outcomes. As far as not understanding the circuits, you are doing the right thing, asking questions. I've learned by asking questions and making mistakes, many mistakes. I still consider myself a rookie at the age of 65. I was in education for 37 years and when I retired I decided I wanted to make my own speakers, I'm learning on the fly. I'll do my best to answer questions, I just hope Marius will jump in if I make an incorrect statement.

@@olobiksnagol2178 Thank you for your reply. Your explanation is the most reassuring I've heard over the past 30 days of asking around. I have posted questions to Marius on this video and he basically told me to go find some other website to answer my questions. I think they are a little too elementary for him. I am planning to put together a pair of GR Research XLS Encore Loudspeakers. We will see how well I do. I am 61 years of age myself. I took Electronics in school and could make zero sense of it. However, I guess the school just didn't want anybody to stick around so I was given a passing grade and was pointed to the exit door. Welcome to American education, right?

I am new to your channel, have subbed and have found your videos refreshing. I am planning to build a Passive 4th order High Pass filter for my tweeter, which is able to play down to 1kHz, and thus I plan to have the signal to be attenuated to 60dB by 1kHz and be at 1.4kHz at 83dB, basically filtering at just below 1.6kHz. Is there a reason why a 3rd order is better suited as a High Pass filter for a tweeter like mine? I have read that when it comes to the phase difference between 4th and 3rd order filters 4th orders can cause resonance, is this correct? I am not 100% sure if I am on the right track and would like to save some money if a 4th order will cause the tweeter to sound weird, but I really like the steep slope, so hoping it is acceptable. Furthermore, I plan to use the following components; Mundorf capacitors Mundorf Air Cored Copper Foil Coils CFC16 (inductors) Mundorf M-Resist Audiophile Resistors Which will cost me a total of $250 for two High Pass Filters. I am happy with the budget but prefer to not waste money making a mistake, especially if it is a blatant one. Thanks for sharing your knowledge.

Years ago I used some hot glue to lock down capacitors, and when I came back to check on them, I found that the speaker vibrations had caused them to pop loose. There are other adhesives that work much better. You can still get the parts off if you have to, but they will not loose their grip the way hot glue can.

Without measuring your drivers inside your box, you cannot design crossovers properly.

@AudioJudgement 3 жыл бұрын

If by conductor you mean inductor, then yes, you can connect them at whatever end. Same for resistors. And the same for capacitors if they are non-polarized. If they are polarized then they have an actual + and - and you need to be aware of that.

@AudioJudgement 9 ай бұрын

You just need to measure your speakers inside the box (acoustically and electrically). You load those measurements into XSim, which is a crossover design app, and you model the crossover design there.

How did you translate what you have drawn at 4:22 to what you have drawn at 8:36? They look nothing like each other. Are they really for the same crossover?

@AudioJudgement 3 жыл бұрын

Yep, it's the same thing. On the circuit diagram you have the amp (input) on the left and the speakers on the right. On the actual crossover (and that piece of paper which I used to sketch the position of the components) you have the input and the speakers all clumped up on the right side. You can imagine that I have to rearrange the components. The connections are the same, the position of the components is different.

You should paint the board with a non conductive flat black paint applied in 26 mil. Layer's measure with a mitutoya model xc34116 if you don't have one a model x 34873 will work if the layers of paint exceed . 002 redo it until you reach the desired tolerance after you do this you may need to tweak it depending on what kind of paint you used
