Audi A3 Sportback e-tron Rear Door Panel Speaker Size
The Audi A3 Sportback e-tron rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers across all listed model years. Compatible audio types for the location include tweeters and midbass or full-range units. The specifications cover a system of model years ranging from 2016 to 2018.
| 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 |
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 rear door panel location in the Audi A3 Sportback e-tron accommodates 2 distinct speaker sizes simultaneously, with the 1-inch and 6.5-inch positions operating as separate mounting points within the same door cavity.
- Door panel installations are typically surface-mounted or flush-mounted within molded cavities, and the rear door position places speakers at a low lateral angle relative to seated passengers, which affects the directional projection of high-frequency content toward the listening area.
- A 6.5-inch driver in a rear door panel occupies a significant portion of the lower door cavity, where the cone's larger radiating surface moves sufficient air to reproduce bass and lower-midrange frequencies effectively within the enclosed door structure.
- The 6.5-inch midbass / full-range type in a rear door position handles the lower portion of the audible spectrum, generally covering frequencies from the upper bass range through the midrange, where wavelengths are long enough to benefit from the acoustic reinforcement of the door cavity acting as a partial enclosure.
- A full-range designation on a 6.5-inch driver indicates the speaker is designed to handle the entire audible spectrum without a crossover, while the midbass designation indicates use within a filtered system where the driver reproduces only low-to-mid frequencies.
- The 1-inch tweeter in the Audi A3 Sportback e-tron rear door panel is positioned at a separate mounting point from the 6.5-inch driver, placing high-frequency reproduction at a physically distinct location within the same door.
- A 1-inch tweeter reproduces high-frequency content, generally above 2,000 to 3,500 Hz, where wavelengths are short and directional dispersion narrows significantly, making the physical mounting angle of the rear door panel relevant to the spatial spread of treble frequencies into the cabin.
- The dome or cone surface of a 1-inch tweeter radiates sound in a narrow forward arc at high frequencies, so the rear door panel's inward-facing angle toward the passenger cabin determines the degree to which treble energy reaches occupants seated in the rear.
- The rear door panel location is a closed structure when the door is sealed, and the internal air volume behind a 6.5-inch driver mounted in the door skin can influence the bass extension and low-frequency resonance behavior of the driver.
- The 2016, 2017, and 2018 model years of the Audi A3 Sportback e-tron share identical rear door panel speaker configurations, with both the 1-inch and 6.5-inch positions remaining consistent across all 3 years.
