Audi S3 Rear Door Panel Speaker Size
The Audi S3 rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers. Compatible types for the audio system include tweeters and midbass / full-range units. These specifications cover the 2015 to 2018 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Tweeter | 1 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Tweeter | 1 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The Audi S3 rear door panel accommodates 2 distinct speaker sizes simultaneously, indicating the location is engineered for a multi-driver configuration rather than a single full-range unit.
- A 6.5 inch driver in the rear door panel occupies the lower portion of the enclosure space, a position that benefits from the door's larger internal cavity, which acts as a partial acoustic chamber for low-to-midrange frequency reproduction.
- The 1 inch tweeter position in the rear door panel places a high-frequency driver within a reflective, hard-surfaced environment, where rear cabin surfaces and seat backs influence the dispersion and arrival time of upper-frequency content at the listening position.
- A 6.5 inch cone driver is physically capable of moving enough air to reproduce frequencies from approximately 40 Hz to 5 kHz, making the midbass and full-range classifications acoustically appropriate for the size at a rear door location.
- Midbass drivers are designed to handle a defined low-to-mid frequency band, typically crossed over to a separate tweeter above approximately 2 kHz to 4 kHz, which aligns with the dual-driver layout documented for the Audi S3 rear door panel.
- Full-range drivers, as a compatible type for the 6.5 inch position, are designed to reproduce the entire audible spectrum without crossover assistance, though a rear door installation may involve acoustic filtering from the door panel material and mounting depth.
- A 1 inch tweeter dome is a high-frequency transducer with a relatively wide dispersion pattern at upper frequencies, generally covering 2 kHz to 20 kHz, characteristics that address the limited high-frequency output of the 6.5 inch driver in the same panel.
- The rear door panel location places both the 1 inch and 6.5 inch drivers below the primary listening axis of seated occupants, a geometrical factor that affects the angle at which high-frequency tweeter output reaches rear passengers.
- Door panel mounting typically constrains installation depth, and a 6.5 inch driver requires sufficient mounting depth clearance to prevent the cone or magnet assembly from contacting the door's inner metalwork during excursion.
- The 2015 through 2018 Audi S3 rear door panel specifications remain consistent across all listed model years, with identical size and type combinations appearing in each row.
