- The 2015 Audi S4 features a multi-component speaker system with tweeters distributed across three locations: dashboard, front door panels, and rear door panels, all sized at 1 inch.
- The factory audio configuration includes a dedicated 2.5 inch midrange speaker in the center dash position, which handles vocal and mid-frequency reproduction.
- Both front and rear door panels accommodate 6.5 inch speakers that accept either midbass or full-range replacements, offering flexibility in component system design.
- The rear deck lid contains two distinct speaker sizes: 3.5 inch full-range units and 8 inch woofers, suggesting a tiered approach to rear soundstage and bass output.
- Replacing the 1 inch tweeters with aftermarket units may provide enhanced high-frequency detail and imaging, particularly for listeners in front seating positions.
- The 8 inch woofer location in the rear deck lid typically handles lower frequency extension, and upgrading this position could improve bass response without requiring subwoofer installation.
- The 6.5 inch door panel speakers represent primary upgrade candidates, as these positions generally contribute most significantly to overall sound quality and staging in factory systems.
- Component speaker systems separating tweeters and midbass drivers would align well with the existing architecture, given the dedicated 1 inch tweeter locations already present in multiple positions.
- The presence of a dedicated center dash midrange speaker indicates the factory system was designed with focused vocal reproduction, which aftermarket installations might maintain or reconfigure.
