Begin by identifying the voice coil–the cylindrical wire winding suspended in a magnetic field. Its diameter, gauge, and material (copper, aluminum, or CCAW) dictate power handling and frequency response. Match the coil’s impedance to the amplifier’s output (typically 4Ω, 6Ω, or 8Ω) to prevent distortion or overheating. Overlook this, and efficiency drops by up to 30%.
