Should the BMW 5 Series opt for the Harman Kardon upgrade?

The BMW 5 Series offers an optional Harman Kardon audio system. Here's more information about the Harman Kardon system: Principle: The internal amplifier circuit divides the sound into several wavelength segments through a crossover. The mid-to-high frequency range (mid-high tones) is output to satellite speakers, while the mid-to-low frequency range (mid-low tones) is output to a subwoofer. Typically, the subwoofer produces long-wave sounds between 20-200Hz, which are easily audible to humans but difficult to localize due to their long wavelengths. Function: Enhances the bass frequency range, boosting the long-wave portion of the audio below 100Hz, including even infrasound. Since regular speakers have limited size and cannot produce longer wavelength low-frequency sounds effectively, a larger subwoofer is required to create impactful low-frequency effects.
