- The 2007 Mercedes-Benz R320 features a factory audio system with dedicated tweeter locations at 1 inch sizing in the D-pillar, front door panels, and rear door panels, suggesting a component-style speaker configuration rather than a coaxial design.
- A 3.5 inch full-range speaker in the center dash position likely handles mid-range frequencies for the soundstage, which could be a candidate for replacement if center imaging or vocal clarity needs enhancement.
- The presence of 6.5 inch speaker locations in both front and rear door panels, plus the cargo area, indicates multiple opportunities for midbass or full-range speaker upgrades throughout the cabin of the 2007 Mercedes-Benz R320.
- Component speaker systems with separate tweeters and midbass drivers would align well with the factory configuration, potentially offering better sound staging and frequency separation than coaxial alternatives.
- The cargo area 6.5 inch speaker position might serve as a rear fill or subwoofer support role, though its classification as midbass or full-range compatible suggests it handles a broader frequency range than a dedicated low-frequency driver.
- Replacing the door panel speakers with aftermarket midbass drivers could improve lower frequency response and overall impact, particularly if the factory units lack excursion capability or cone rigidity.
- The multiple tweeter locations throughout the cabin suggest that maintaining or upgrading these 1 inch components could affect high-frequency dispersion and soundstage width across different seating positions.
