- The 2018 Audi S7 factory audio system incorporates a three-way speaker configuration in the front doors, with separate tweeters, midrange drivers, and midbass components handling different frequency ranges for potentially improved sound staging and clarity.
- Tweeter locations are distributed across multiple positions including the center dash, dashboard corners, and rear door panels, which may contribute to enhanced high-frequency dispersion throughout the cabin.
- The center dash contains both a 1-inch tweeter and a 3.5-inch full-range speaker, suggesting a dual-purpose design that handles both high frequencies and broader mid-range reproduction in the central soundstage.
- Rear door panels feature both 1-inch tweeters and 6.5-inch midbass or full-range speakers, providing rear passengers with a two-way speaker system rather than single-driver coverage.
- The C-pillar mounting location for 3.5-inch midrange speakers may create a wider soundstage by positioning mid-frequency drivers away from the traditional door panel locations.
- An 8-inch subwoofer in the cargo area suggests factory provisions for low-frequency extension, though aftermarket replacement options in this size category could offer improved bass response and output capability.
- The 6.5-inch midbass speakers in both front and rear door panels represent the largest drivers in the door-mounted system and would likely benefit most from aftermarket upgrades focused on cone material quality and motor structure improvements.
- Component speaker systems with separate tweeters and woofers would align well with the existing three-way front door architecture, potentially simplifying installation while maintaining the factory's frequency division approach.
- The variety of speaker sizes and types indicates a complex factory audio design that may require attention to sensitivity ratings and impedance matching when selecting aftermarket replacements to maintain proper system balance.
