Field coil quandry
#1

Other than resistance value, is there another consideration to a field coil?

Here's why I'm asking: If I have, for instance, an 8" speaker with a field coil resistance, of say, 5000Ω, at around 15W, can I replace it with an 8" speaker with the same wattage, but only 1000Ω? And just add a 4000Ω resistor of around 10W, with possibly increasing the size of the filter cap, also?
