It's like a very expensive high performance car and you go and put a set of bargain basement walmart tires on it.
My comment was intended to indicate that since he's using silver wire he should continue with a termination of equal conductivity.
and furthermore it's interesting that the tarnish on silver is equally conductive.
Cheers to all
Let`s calculate the Resistance of the plating on a connector like a Cardas spade. ( I used the dimensions from model CGMS R )
The resistivity (rho) of pure silver is 1.591E-08 per meter.
The resistivity (rho) of pure rhodium is 4.490E-08 per meter.
The area of contact of the spade is about 8.4E-05 square meters. This is Cross sectional Area of the conductor.
The thickness of the plating can be estimated at say 0.1 mm. or 1E-04m. This is length of conductor.
Resistance in ohms = rho * Length/cross sectional area
For silver this is 1.591E-08 * 1E-04/8.4E-05 = 1.89405E-08
For Rhodium this is 4.490E-08 * 1E-04/8.4E-05 = 5.34524E-08
Remember, E-08 means x 10 to the negative 8th power. Which means you shift the decimal place 8 places to the left.
So silver is 0.0000000189405 ohms, rhodium is 0.0000000534524 ohms.
Resistance of the coating does not matter. There is certainly greater variation in the components of the crossover and speaker.
