- The 2013 Audi S4 utilizes a multi-speaker configuration with dedicated tweeters positioned in the dashboard and both door panels for high-frequency reproduction.
- A 2.5 inch midrange driver in the center dash handles mid-frequency vocals and instruments, working in conjunction with the tweeter array.
- Both front and rear door panels incorporate 6.5 inch drivers that can accommodate either midbass or full-range replacements depending on the desired sound characteristics.
- The rear deck lid features dual speaker locations with a 3.5 inch full-range driver and an 8 inch woofer for extended low-frequency response.
- Replacement of the 6.5 inch door panel speakers may provide the most noticeable impact on overall sound quality, as these handle the critical mid-bass frequencies.
- The tweeter locations suggest a factory component system design rather than simple coaxial speakers throughout the cabin.
- Upgrading the 8 inch rear deck woofer could enhance bass output for listeners preferring stronger low-end extension.
- The presence of dedicated midrange and midbass drivers indicates potential for three-way component speaker upgrades in the front soundstage.
- Factory speaker sizes vary considerably from 1 inch tweeters to an 8 inch woofer, reflecting frequency-specific driver allocation.
