I solder at 450 , at least thats whats indicated on the display. I was soldering 18g wire. That is fine to do it that way but i find it gets the components pretty hot so i start with the tip on top add solder and thenmove the tip underneath to draw the solder through. Nothing wrong with how your doing it , maybe im wrong lol.

I'll try 450 out with melting the solder into the joint with direct heat. I'm not sure there's a right or wrong way. Just what works. smile

I watched a bunch of vids and practiced a bit. Some of the vids I saw were Naval grade repairs.... Overkill soldering for what we are into. I just dont wanna buy capacitors again. Visa needs to heal.


Edit:
Tried it your way with 600F (450 wont melt this 60/40 solder quick enough when tinning the iron.) Great stuff. Not as hot outside of joint and solder still boiled right into this 14 stranded test. Perfect. Thanks!

that looks perfect to me. Were just trying to make the solder stick to the wire and flux is your friend.Real sense of satisfaction when you solder up a crossover and you get beautiful music.

Also watch your tip at that temp, i find it gets a black coating which will insulate the tip and make soldering difficult. I usually dip the tip in the flux and then rub it on my jeans. Sometimes i even need a little sand paper to clean the tip up.

Wow, brings back memories of my early days in electronics, back when we would actually repair devices, PCB's, etc.

Not sure if this is still a valid tip, but a trick I used decades ago to protect a component from heat damage by placing a heat sink between the joint and the component. This can be as simple as an alligator clip.

YMMV

Some parts came. Crossovers built. Still waiting on drivers.

The crossovers will be external and I plan on building cigar boxes for them that will sit on the floor behind the towers. I will probably tart up the boxes to make them all purdy so I have the option later to have them out in the open. It will be like a kid dragging a wagon kinda setup. Toying with the idea of a mirror finish on all this stuff. A once in a life grievance! lol.

I opted to mount the components to rubber mat rather than the traditional scrap of wood or cardboard so I can test fit them in the boxes and remove as needed. I will glue the mat in when ready with GE silicone II. FWIW the Solen stuff is all higher quality than the Dayton and ERSE stuff I ordered from parts express. Solen just didn't have all the values I needed.

These mats are pretty sweet for vibration reduction I would think. The knobby side will face down. $8 Canadian Tire. My index finger looks like the very hungry caterpillar in the pic. Good stuff!



Here is what a hole in the wallet looks like. laugh



And the assembled crossovers. Does anyone else know how to read a schematic to double check em for me? Would appreciate it. smile Will send better pics and schematic.



Onward ho!

I screwed up on the first crossover i built for my center channel. I didnt catch it until much later when i ran Dirac and i kept getting a weird dip in my midrange. It turned out i had soldered 2 caps in series which is a no no. What a difference that made im here to tell ya. This is how we learn though. Post the parts list and the diagram and i will have a look,always good to have a second opinion or even a third if someone else wants to take a look see. I see you got a circle guide, those are so handy. That damn MDF is brutal on router bits, i really had to learn to slow down on my impatience .

Awesome! I was hoping you would offer but I didn't want to impose. smile The solder tips like sanding the tip and alligator clips worked great you guys.

Here are the pics. Best I could do to make the parts values visible with schematics in a way that was usable. The pics scaled weird when loaded into the forum but you can zoom using control and +. To go back control and -.
