  • Why do both Light Harmonic and Tesla OEM speakers feature a unique low impedance design? [Technical]
    The low impedance design found in both Light Harmonic and Tesla OEM speakers isn't a random choice - it's a strategic design decision. In general aftermarket car speakers, you will see speakers rating at 8 Ohm to 4 Ohm usually. On the other hand, Light Harmonic and Tesla OEM speakers are designed to be lower impedance speakers, generally rated below 3 or even 2 ohms, can handle more power and provide more volume than their higher impedance counterparts. In the context of a vehicle, where background noise is a significant factor, this increased power handling and volume output are particularly beneficial. By effectively using the power from the amplifier, low impedance speakers ensure optimal performance, delivering a dynamic, high-quality audio experience even amidst road noise. Impedance, measured in ohms (Ω), is a measure of the opposition that a circuit presents to the flow of current when a voltage is applied. In audio systems, lower impedance means less resistance to the power supplied by the amplifier. Our speakers, all door woofer or subwoofer are designed at 1.2 Ohms in effective frequency or even lower, can draw more current from the amplifier and handle more power compared to higher impedance speakers. This essentially allows more energy to be converted into sound, not heat, leading to greater volume output and potentially better sound quality. In terms of transient response – the speaker's ability to respond to changes in the audio signal – lower impedance offers an advantage. This is because transient response is linked to the speaker's control over the motion of the diaphragm. More current flow, allowed by low impedance, can provide better control of the speaker diaphragm, leading to more accurate sound reproduction, especially during complex or fast-changing audio passages. Therefore, Light Harmonic's choice to employ a low impedance design aims at ensuring an optimal, high-quality audio experience that is both powerful and faithful to the original audio source. The benefits of low impedance speakers, such as those designed by Light Harmonic, lie in the realms of power handling, volume output, and transient response.
