Dunlavy SC IVA X-over resistor values

First mark them carefully - so you know exactly where they are mounted. Then take them out (solder gun and sucker tool) and simply measure them with a multimeter. You may need to buy several resistors to find something that is very close. Normally resistors have +/- tolerances. Good luck - and make sure you pay attention to the power ratings too.

Or just look at the color rings. Plenty of websites where you can decode the colors. The values may have drifted over the years so what you measure may not be within tolerance of the nominal value. Also, if the quality of you solder joints is anything less than the factory, it could negate any advantage of a better resistor.

Shadorne, why can't you just measure them in place at the shoulders without removing them? I didn't think it would throw it off that much.

Thank you all for this. I do appreciate it. I'm new to this. I did have the connections to the actual speaker elements soldered and that made a nice improvement in the sound. Removed a kind of rizz or roughness I had not noticed until it was gone. These speakers have a wonderful top to bottom consistency or coherence I haven't heard before in a cone speaker. I have heard other speakers do certain things better but not overall. The bass quality is very accurate as well. Again, thanks for your input and if you have more data on this it would be welcome. This speaker is worth every minor improvement added to it. Jonathan
