Audi S5 Sportback Front Door Panel Speaker Size
The Audi S5 Sportback front door panel accommodates a 3.5 inch speaker size and supports 6.5 inch speakers as well. Compatible types across these locations include midrange and midbass / full-range units. These specifications cover the 2018 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midrange | 3.5 |
| 2018 | 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 front door panel of the Audi S5 Sportback accommodates 2 distinct speaker sizes, each occupying a separate mounting location within the door structure.
- A 3.5 inch mounting location exists in the front door panel, a diameter associated with smaller drivers typically positioned in upper door or sail panel areas to maintain proximity to ear level for focused midrange reproduction.
- The 6.5 inch mounting location in the front door panel represents a larger baffle cutout, a diameter that generally requires greater door cavity depth and surface area to seat the basket and allow adequate rear cone excursion.
- The 3.5 inch position in the Audi S5 Sportback front door panel is designated for midrange drivers, which handle frequencies roughly between 500 Hz and 5 kHz, the band responsible for vocal presence, instrument body, and speech intelligibility.
- Midrange drivers at 3.5 inches operate with a relatively controlled dispersion pattern, which is acoustically relevant in a door panel location where the driver faces across the footwell toward the listening position.
- The 6.5 inch location supports midbass or full-range driver types, with midbass units concentrating on the lower midrange and upper bass frequencies, roughly 80 Hz to 500 Hz, where kick drum, bass guitar fundamentals, and lower vocal harmonics reside.
- A full-range driver in the 6.5 inch front door location would span a wider frequency band than a dedicated midbass unit, typically attempting coverage from the upper bass region through portions of the midrange without a dedicated crossover network.
- The 6.5 inch cone surface area is substantially larger than the 3.5 inch cone, which allows greater air displacement and supports lower-frequency reproduction from within the door cavity before acoustic output drops off.
- Front door panel locations inherently place larger drivers near the floor of the vehicle interior, a position where low-frequency wavelengths are less directional and the door skin and window glass act as boundary surfaces that can influence bass loading.
- The separation of the 3.5 inch midrange and the 6.5 inch midbass or full-range positions within the same front door panel reflects a two-point speaker layout across the door's vertical axis.
