Dual-band in-car speakers are designed to split the incoming audio signal into two parts, allowing for more accurate music reproduction. They consist of two separate drivers integrated into one unit or supplied as a set. The larger, mid-bass transducer takes care of reproducing low and mid frequencies such as bass and vocals. The smaller, tweeter, often referred to as a 'tweeter', specialises in high frequencies such as cymbal sounds or hiss. Dividing the work between the two specialized transducers results in a cleaner, more detailed sound, as one all-purpose speaker cannot effectively cover the entire audible spectrum from deep bass to the highest notes. A component called a frequency shifter makes sure that the frequencies are properly divided. This ensures that only the high notes reach the tweeter and the low and mid tones reach the mid-bass. There are two basic types of two-way speakers. In coaxial speakers, the tweeter is placed directly in the middle in front of the mid-bass transducer, forming one compact piece for easy installation. The second type is component systems, where the midrange and tweeter are physically separated. This allows the tweeter to be placed in a different location, such as on the dashboard or door pillar, bringing the soundstage closer to the listener's ear level and improving the spatial perception of the music.
