Ideally you need exact same number of turns as there are in your voice coil. As then the hum current in one will be the exact opposite of the other and they will cancel.
Unless someone knows for sure: you could possibly make a 5-turn coil with long leads, determine the right polarity (by swapping ends) and then by adding or subtracting turns see where the optimum value is.
