Audi A4 allroad Rear Side Panel Speaker Size
The Audi A4 allroad rear side panel accommodates an 8 inch speaker size across all listed model years. Compatible types for the location include woofer replacement units suited for the audio system. These specifications cover the 2017 to 2018 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Woofer | 8 |
| 2017 | Woofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| Woofer | A larger driver for low frequencies, typically from about 40 Hz up to 1,000 Hz. It delivers most of the bass and lower midrange in a door or panel speaker system. |
Additional Notes
- The rear side panel location in the Audi A4 allroad is a dedicated enclosure position integrated into the vehicle's interior side structure, placing speakers within a partially enclosed cavity that affects bass loading and low-frequency output efficiency.
- An 8-inch woofer in the Audi A4 allroad rear side panel operates within a mounting space sized to accommodate the larger cone diameter and deeper basket depth that 8-inch drivers typically require compared to smaller midrange units.
- The rear side panel position places speakers along the lower lateral sections of the cabin, a location that tends to reinforce low-frequency energy through proximity to the floor and side panels, which act as acoustic boundaries.
- An 8-inch driver produces a larger cone surface area than smaller alternatives, allowing greater air displacement and stronger reproduction of bass and upper-bass frequencies, generally spanning the range below approximately 500 Hz.
- Woofers are loudspeaker drivers engineered specifically for low-frequency reproduction, typically covering the bass portion of the audio spectrum and operating most efficiently when mounted in an acoustically supportive enclosure or semi-enclosed space.
- The rear side panel mounting orientation affects the directional dispersion of low-frequency output, as woofers at this location project sound laterally into the cabin rather than forward toward the listening position.
- At 8 inches, the driver's physical depth and magnet assembly dimensions are significant factors in rear side panel fitment, as the available depth behind the mounting surface must accommodate the full basket and motor structure without obstruction from structural elements.
- The woofer designation for the rear side panel position in the 2017 and 2018 A4 allroad indicates the location is not configured for full-range or high-frequency reproduction, functioning instead as a dedicated bass reinforcement point within a multi-speaker system.
