Audi S3 Front Door Panel Speaker Size
The Audi S3 front door panel accommodates 3.5 inch speaker size and 6.5 inch units across all listed model years. Compatible speaker types for these locations include midrange, midbass, and full-range audio system units. These specifications cover the 2015 to 2018 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midrange | 3.5 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Midrange | 3.5 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midrange | 3.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midrange | 3.5 |
| 2015 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 front door panel accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver configuration within the door cavity.
- A 3.5 inch driver mounted in the Audi S3 front door panel occupies a physically compact footprint, which suits placement in the upper or mid-section of a door panel where cone excursion space and baffle depth are typically limited.
- The 6.5 inch position in the front door panel of the Audi S3 is consistent with a lower door mounting point, where the larger baffle area and deeper cavity accommodate the greater cone displacement required for low-to-mid frequency reproduction.
- Midrange drivers operating in a 3.5 inch format are acoustically suited to reproducing frequencies roughly between 500 Hz and 5 kHz, covering the vocal and upper-instrumental range with relatively controlled directional dispersion at the front door panel's typical listening axis.
- A 3.5 inch midrange driver produces a relatively narrow radiation pattern at higher frequencies, which at the front door position means the driver's output is directionally focused toward the listening cabin rather than diffused broadly.
- The 6.5 inch position supports midbass drivers, which handle the frequency band approximately between 80 Hz and 500 Hz, a range that benefits from the larger cone area and the acoustic loading the door's internal cavity can contribute at low frequencies.
- Full-range drivers, also listed as compatible with the 6.5 inch position, are designed to reproduce a wide frequency span from bass through upper midrange within a single driver, relying on the cone size to maintain output at lower frequencies while a dust cap or whizzer cone extends high-frequency response.
- The coexistence of a 3.5 inch midrange and a 6.5 inch midbass or full-range driver in the same front door panel indicates a configuration where frequency responsibilities are divided across separate physical locations within a single door structure.
- In a front door panel installation, the 6.5 inch driver's larger moving mass and cone area generate the acoustic output levels at lower frequencies that a 3.5 inch cone cannot achieve due to its smaller radiating surface.
- The front door panel location places drivers within the lower portion of the vehicle's interior soundstage, and the 3.5 inch midrange at that position contributes upper-frequency detail from a physically lower angle relative to seated occupants.
