Audi S7 Rear Door Panel Speaker Size
The Audi S7 rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers across all listed model years. Compatible types for the audio system include tweeters and midbass or full-range replacement units. The specifications cover a range from 2013 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 |
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Tweeter | 1 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Tweeter | 1 |
| 2013 | 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 S7 rear door panel accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver mounting configuration within the door panel structure.
- Door panel installations are spatially constrained by the interior door cavity depth and the structural framework of the panel itself, which determines the available mounting depth and baffle surface area for each driver position.
- The 6.5 inch position in the Audi S7 rear door panel is sized to handle midbass and full-range reproduction, a diameter range typically capable of resolving frequencies from approximately 60 Hz up to 5 kHz depending on cone material and crossover configuration.
- A 6.5 inch driver mounted in a rear door panel operates within an enclosure formed by the door cavity, where the internal volume and panel rigidity directly influence low-frequency extension and resonance behavior.
- The midbass type designation for the 6.5 inch position indicates a driver optimized for the lower-midrange and upper bass frequencies, typically crossed over to a subwoofer below and a tweeter above, reducing the excursion demands placed on the cone.
- Full-range compatibility at the 6.5 inch position means a single driver at that location can cover the broad audible spectrum without requiring additional crossover components, though rear door placement affects stereo imaging due to the lateral and low listening angle relative to seated passengers.
- The 1 inch tweeter position in the Audi S7 rear door panel places a high-frequency driver at door panel height, a mounting location that affects the vertical dispersion angle of treble frequencies reaching rear seat passengers.
- A 1 inch tweeter is associated with high-frequency reproduction, generally covering the range from approximately 2 kHz to 20 kHz, where wavelengths are short enough that driver diameter has a significant effect on directional dispersion.
- At 1 inch, the tweeter diaphragm maintains relatively wide horizontal dispersion across the upper frequency range, which is relevant in a rear door location where the listening axis is not directly aligned with the driver face.
- The tweeter type designation specifies a driver constructed for high-frequency-only operation, typically using a dome or cone diaphragm with a crossover or built-in filter to block low-frequency signals that would damage the small voice coil and diaphragm assembly.
- The combination of a 1 inch tweeter and a 6.5 inch midbass or full-range driver within the same rear door panel represents a 2-way speaker layout, where each driver handles a separate portion of the frequency spectrum from a shared mounting location.
- Rear door panel placement positions both drivers closer to the rear passenger seating zone than front door or dashboard locations, affecting the perceived sound stage depth and the direct-to-reflected sound ratio experienced by rear seat occupants.
