What Speaker Impedance Means and Why it Matters

1. 1. Speaker impedance refers to the opposition to electric current flow within the speakers.
   2. Measured in ohms, speaker impedance defines the relationship between an AV receiver or amplifier with connected speakers.
   3. Impedance must be the same for the speakers and the AV receiver. Any mismatch causes distortions in sound output.
   4. A 4 ohms speaker connected to an 8 or 16 ohms AV receiver for instance is disastrous.
   5. The speaker will strain to match the output of the AV receiver which has a higher impedance.
   6. While pushing hard to produce sound, the speaker overheats which damages and leads to its failure.
   7.  It is therefore advisable to always get receivers and speakers with matching impedance.
