Additional Notes
- The 1979 Mercedes-Benz 450SL contains two distinct speaker locations with different size requirements, suggesting a basic two-way audio configuration from the factory.
- Dashboard speakers at 4 inches are designated for midrange frequencies, indicating these drivers may handle vocal and instrumental content in the middle frequency spectrum rather than attempting full-range reproduction.
- The rear deck lid accommodates 4x6 inch full-range speakers, which likely serve as the primary source for broader frequency coverage including bass response within the limitations of this compact oval format.
- Aftermarket replacement options for the dashboard position would benefit from midrange-specific drivers that optimize output between approximately 300Hz and 5kHz, where human hearing is most sensitive.
- Full-range speakers in the rear deck position face the inherent challenge of reproducing low frequencies adequately through a 4x6 inch cone area, which may limit bass extension compared to larger formats.
- The single DIN radio opening provides standard compatibility with most aftermarket head units, potentially allowing for improved source quality and amplification to drive replacement speakers more effectively.
- Upgrading the rear deck speakers to higher-sensitivity models could produce noticeable improvements in overall volume and clarity, as these drivers handle the majority of the frequency range.
- Component speaker systems are not indicated by the factory configuration, though the separated midrange drivers in the dashboard suggest the possibility of adding tweeters for enhanced high-frequency extension.
