Audi S3 A-Pillar Speaker Size
The Audi S3 A-Pillar location accommodates a 1 inch speaker size, consistent across all model years. Compatible types for the A-Pillar audio system include tweeter units. These specifications cover the 2015 to 2018 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2017 | Tweeter | 1 |
| 2016 | Tweeter | 1 |
| 2015 | Tweeter | 1 |
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. |
Additional Notes
- The A-pillar location in the Audi S3 positions speakers at the uppermost sides of the windshield frame, placing drivers near ear level and angling sound directly toward the listening position.
- A-pillar mounting is a fixed, structurally integrated location, meaning the available cavity depth and baffle width are constrained by the pillar's molded trim dimensions.
- The 1-inch diameter specified across all listed model years of the Audi S3 A-pillar reflects the compact physical footprint required to fit within the narrow cross-section of the A-pillar trim pod.
- A 1-inch driver in an A-pillar position places the high-frequency source at a forward, elevated angle relative to the listener, which supports stereo imaging and soundstage width.
- Tweeters are dedicated high-frequency drivers, typically reproducing frequencies from approximately 2,000 Hz up to 20,000 Hz or beyond, covering the upper range of audible sound where harmonics, vocal sibilance, and transient detail reside.
- The tweeter's small diaphragm mass allows rapid pistonic movement, which is acoustically necessary for accurate reproduction of short-wavelength, high-frequency signals.
- At high frequencies, sound becomes increasingly directional, and the A-pillar placement of a tweeter in the Audi S3 A-pillar aligns the driver's primary radiation axis toward the occupants rather than reflecting off surfaces first.
- The 1-inch format is a standard tweeter diameter that balances high-frequency extension with controlled dispersion, avoiding the narrow beaming that can occur with larger dome sizes at elevated frequencies.
- The A-pillar location separates the tweeter physically from mid-range and woofer drivers typically mounted lower in the door or kick panel, which supports crossover-based frequency division in a multi-driver system.
- The tweeter type is the only compatible speaker type listed for the Audi S3 A-pillar across the specified model years, indicating the location is acoustically and spatially suited exclusively to high-frequency reproduction.
