Toyota 86 Rear Side Panel Speaker Size
The Toyota 86 rear side panel location accommodates a 2.5 inch speaker size across all listed model years. Midrange units represent the compatible audio system type for the rear side panel. These specifications cover the 2017 to 2018 model year replacement chart range.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midrange | 2.5 |
| 2017 | Midrange | 2.5 |
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. |
Additional Notes
- The rear side panel location in the Toyota 86 accommodates a 2.5-inch speaker cutout, which is a notably compact mounting cavity relative to typical automotive speaker positions.
- A 2.5-inch driver in a rear side panel position operates within a physically constrained enclosure formed by the panel's interior cavity, which limits the available air volume behind the cone.
- The 2.5-inch size, as applied to the Toyota 86 rear side panel, is associated exclusively with midrange driver types across the listed model years.
- Midrange drivers are designed to reproduce frequencies roughly between 300 Hz and 5,000 Hz, covering the portion of the audio spectrum that includes vocals, instruments, and much of the presence region.
- A 2.5-inch midrange driver produces relatively directional sound at the upper end of its frequency range, meaning placement within the rear side panel affects the perceived stereo imaging from the listening position.
- The rear side panel location positions the speaker low and rearward in the cabin, which influences the angle and distance from front-seat occupants relative to the primary listening axis of the driver.
- At 2.5 inches, the cone surface area is small, which limits low-frequency extension and output volume, making the driver dependent on other system components for bass reproduction in a full-range setup.
- Midrange drivers are typically not designed for high excursion, and in a sealed rear side panel cavity, cone movement is further mechanically restricted by back-pressure from the enclosed space.
- The Toyota 86 rear side panel's 2.5-inch midrange specification applies to both the 2017 and 2018 model years, indicating dimensional consistency in the mounting location across those 2 years.
