Additional Notes
- The 1973 Mercedes-Benz 450SE dashboard locations accommodate 4-inch midrange speakers, which suggests a factory focus on mid-frequency reproduction rather than full-spectrum audio in forward positions.
- Rear deck lid positions in the 1973 Mercedes-Benz 450SE accept 4x6 inch full-range speakers, indicating these locations likely handle broader frequency response including bass and treble components.
- The combination of dedicated midrange units in the dashboard and full-range speakers in the rear deck lid represents a distributed audio approach where different frequency ranges may be emphasized at different listening positions.
- Replacing the dashboard midrange speakers could improve vocal clarity and instrumental definition, as these frequencies typically occupy the 300Hz to 5kHz range where human hearing is most sensitive.
- The 4x6 inch rear deck speakers, being full-range types, would benefit from replacements featuring extended bass response and silk or soft-dome tweeters for smoother high-frequency output.
- The Single DIN radio specification indicates a standard 2-inch tall head unit opening, which allows for various aftermarket receivers with potentially improved amplification and equalization capabilities.
- Upgrading both speaker sets simultaneously might provide more noticeable sonic improvements than addressing individual locations, as tonal balance across the cabin would remain more consistent.
- The 4-inch midrange format limits low-frequency extension due to cone surface area constraints, suggesting these drivers primarily support upper bass through lower treble reproduction.
