Additional Notes
- The dashboard location in the 1974 Mercedes-Benz 450SL accommodates 4-inch midrange speakers, which typically handle mid-frequency audio content rather than the full frequency spectrum, suggesting that low-frequency reproduction may be limited in this position.
- Rear deck lid mounting positions accept 4x6 inch full-range speakers, indicating these units would process the entire audible frequency range and likely serve as the primary sound source for rear seat passengers.
- The full-range designation for rear deck speakers suggests these positions may offer more complete sound reproduction compared to the midrange-only dashboard speakers, potentially making rear deck replacement a higher priority for overall audio quality enhancement.
- A single DIN radio opening provides standard aftermarket head unit compatibility, though the specific speaker configurations would still need to match the factory cutout dimensions to avoid modification requirements.
- The combination of midrange and full-range speaker types indicates a factory audio design that splits frequency responsibilities between different locations rather than employing uniform speaker types throughout the cabin.
