Help a poor noob pls!

So, as promised, some photos below...

I would expect the resistor AND capacitor to make a larger difference than the inductors. I'd change both. I've had good luck with the Mills resistors, others with some of the Caddocks. Either will be smoother and better defined than the sand cast cheapies.

Thanks for the advice. I am not sure whether I checked the DC resistance before ordering - I may not have been paying enough attention to what people had written. However, everything sounds okay, so maybe I got lucky!

You might want to consider replacing what appears to be a steel mounting plate with a plastic or aluminum one. I distrust steel/ferrous metals, especially as you are going to air core coils, which have a larger magnetic field coverage volume than cored coils. Ordinary steel (not designed for use in magnetic applications) tends to have hysteresis and nonlinear loss issues.

Thankfully, the back plate is plastic, not metal so there shouldn't be any weird interference issues. Most of the new components seem to be bigger than the old ones, other than the resistors. I did have one scare when trying to put the first crossover back into the cabinet... and the bottom resistor stuck out by half an inch! Then it slid up a little further and just squeezed home. I made sure to solder the second one a little further up the board.

When testing speakers after a change of crossover, use a very low volume (in case you messed up), better now blow another tweet !

Very wise advice indeed... I was more than a little nervous and used a tiny volume to start with. I shall keep the volume low for a few hours and then wind it up a little. I am not going to be able to avoid hearing the speakers during run-in as they are in my office and I need music to work. I shall just have to try and remember what the old ones sounded like (a dodgy proposition, I know)


And now, the pics:

Missed out the larger Dayton cap here

Notice the very classy use of zipties and bubblewrap to hold the coils in place 😛 Everything was soldered back onto the board.

Thanks again for all the help!
