Is the Difference Between Seat Subwoofer and Trunk Subwoofer Significant?
1 Answers
Seat subwoofers and trunk subwoofers do not differ significantly, and trunk installation is generally preferred with appropriate volume levels. Below is an introduction to car subwoofers: 1. Principle: The internal amplifier circuit divides sound into several wavelength segments through a crossover. The mid-to-high frequency segments (mid-high tones) are output to satellite speakers, while the mid-to-low frequency segments (mid-low tones) are output to the subwoofer. Typically, a subwoofer produces long-wave sounds between 20-200Hz, which are easily heard but difficult to localize due to their long wavelengths. These long-wave sounds are transmitted through a bass reflex port, resonating with satellite speakers. The combined weak bass from the subwoofer and satellite speakers is then reproduced by the satellite speakers, creating a vibrant bass effect that seems to originate from the satellite speakers. 2. Function: The subwoofer enhances the low-frequency range, particularly the long-wave segments (below 100Hz, including infrasound, which is inaudible but effective). Since regular speakers, limited by size, cannot produce low-frequency sounds with longer wavelengths, a larger subwoofer is required to generate intense low-frequency effects. Additionally, bass waves, being the longest, have lower efficiency in energy conversion, making them more power-consuming to produce the same output power, thus requiring higher input power.
