Audi S5 Sportback Rear Door Panel Speaker Size
The Audi S5 Sportback rear door panel accommodates a 0.75 inch speaker size and supports 6.5 inch speakers. Compatible types across these locations include tweeter and midbass / full-range audio units. These specifications cover the 2018 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 0.75 |
| 2018 | 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 S5 Sportback accommodates 2 distinct speaker sizes, each serving a separate frequency role within the same mounting zone.
- A 6.5 inch speaker in a rear door panel occupies a mid-to-lower position within the door cavity, typically mounted in a dedicated baffle or bracket behind the door card, where the enclosure volume of the door interior influences low-frequency output.
- The 6.5 inch diameter is a standard mid-woofer size, capable of reproducing frequencies from approximately 50 Hz to 5 kHz, making midbass and full-range designations acoustically appropriate for a rear door panel position.
- In a rear door panel, the 6.5 inch driver handles the lower midrange and midbass content directed toward the rear cabin, where reflected sound from side panels and seating surfaces contributes to the overall soundstage.
- A 0.75 inch tweeter in the rear door panel occupies a separate, smaller cutout positioned higher on the panel surface, designed to project high-frequency content toward the rear passenger area.
- The 0.75 inch tweeter size operates in the high-frequency range, typically from around 3 kHz to 20 kHz, and at that diameter produces a relatively wide dispersion pattern suited for near-field rear passenger coverage.
- Tweeters mounted in rear door panels are positioned to aim high-frequency sound directly at rear seat occupants, a placement that reduces the absorption effect of seat materials on treble frequencies.
- The Audi S5 Sportback rear door panel specs for 2018 indicate that the tweeter and midbass/full-range positions are separate cutouts, meaning a 2-driver per door configuration is used at the rear.
- The midbass designation on the 6.5 inch position indicates the driver is expected to handle frequencies below the crossover point assigned to the 0.75 inch tweeter, with the two drivers operating as a component-style split rather than a single full-range unit.
- Door panel speaker locations are constrained by panel thickness, inner door skin depth, and the structural elements of the door frame, all of which determine the maximum allowable mounting depth for any driver installed at the 6.5 inch or 0.75 inch positions.
