Should You Opt for the Harman Kardon Sound System in the BMW 5 Series?
2 Answers
The BMW 5 Series offers the option to upgrade to a Harman Kardon sound system. Below is more information about the Harman Kardon system: 1. Principle: The internal amplifier circuit divides the sound into several wavelength segments using a crossover. The mid-to-high frequency range (mid-high tones) is directed to the satellite speakers, while the mid-to-low frequency range (mid-low tones) is sent to the subwoofer. Typically, the subwoofer produces long-wave sounds between 20-200Hz, which are easily audible to the human ear. However, due to their long wavelengths, it is difficult to pinpoint the direction of the sound source. These long-wave sounds are emitted through a bass reflex port, resonating with the satellite speakers. The combination of the weak bass produced by the long-wave speaker and the satellite speakers allows the satellite speakers to reproduce the bass, resulting in a powerful and immersive bass effect that feels as if it is emanating from the satellite speakers. 2. Function: The system enhances the bass frequency range, improving the long-wave portion of the audio (below 100Hz, including infrasound). Since conventional speakers have limited size and cannot produce longer-wavelength low-frequency sounds, a larger subwoofer is required to generate intense low-frequency effects. Additionally, bass sound waves have the longest wavelengths, resulting in lower efficiency during energy conversion. Producing these waves is highly energy-intensive, meaning a higher input power is needed to achieve the same output power level.
When considering whether to opt for the Harman Kardon sound system in the BMW 5 Series, I approach it from a music experience perspective: As someone who enjoys listening to music while driving, I spend a significant amount of time in the car. The standard audio system often sounds muffled with blurred details, whereas the Harman Kardon makes a noticeable difference. It delivers crisper instrumentals and clearer vocals, especially during long highway drives, preventing ear fatigue. After comparing it to the standard version while playing a high-quality lossless track, the Harman Kardon creates a surround-sound effect—akin to using premium speakers at home—making the immersive experience worth the cost. However, it does add several thousand yuan to the price tag, which might seem extravagant if you mostly listen to radio or simple pop music. But if your budget allows and you frequently drive for trips or gatherings, this upgrade can elevate the overall driving pleasure. Don’t overlook its detail resolution: It reduces distortion, tightens the bass, and turns driving into not just a way to pass time but also an artistic enjoyment.
