I'm have a delima, I'm not sure which type of resistor to order. I will be using them for an Adire speaker kit, I'm lookinf for a warm sound, lively, dynamic sound. Any suggestions?
The difference is so small that you shouldn't worry about it - just get the most easily accessible/cheapest variety. We have enough trouble agreeing if the capacitors are noticeable.
Resistors only need to be non-inductive and have enough heat dissipation to handle the current going through them. Most resistors sold for speaker building can handle the power.
