Overheating typically results from excessive power input, impedance mismatch, poor ventilation, or DC offset in audio signals, which can degrade adhesives and damage insulation.
Impedance determines power transfer efficiency; mismatched impedance causes power loss, frequency response irregularities, and potential amplifier damage.
Generally not recommended; damaged coils require complete replacement due to precision winding requirements and adhesive bonding integrity.
