Scion xD Front Door Panel Speaker Size
The Scion xD front 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. These specifications cover the 2008 to 2014 chart of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2014 | Tweeter | 1 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Tweeter | 1 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Tweeter | 1 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Tweeter | 1 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Tweeter | 1 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Tweeter | 1 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Tweeter | 1 |
| 2008 | 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 Scion xD front door panel accommodates 2 distinct speaker sizes simultaneously, with the 6.5 inch position and the 1 inch position occupying separate mounting locations within the same door panel.
- Front door panels mount speakers against the interior cabin wall, placing drivers in a lateral position relative to the listening position, which affects the angle and distance of sound projection toward occupants.
- The 6.5 inch diameter indicates a woofer-class cone area large enough to move sufficient air for low-to-mid frequency reproduction, making the front door panel a structurally load-bearing surface for the heaviest driver in the installation.
- A 6.5 inch front door placement positions the low-frequency driver near floor level, which is a common acoustic condition in door installations where bass frequencies radiate upward and outward into the cabin footwell and seating area.
- The midbass role assigned to the 6.5 inch position focuses output on frequencies roughly between 80 Hz and 500 Hz, covering the lower midrange and upper bass registers that carry fundamental tones of vocals, bass guitar, and kick drum.
- When the 6.5 inch position operates in full-range mode, the driver extends coverage beyond the midbass band, reaching into midrange frequencies and reducing the dependency on a separate dedicated midrange driver elsewhere in the vehicle.
- The 1 inch tweeter size in the Scion xD front door panel indicates a small-diameter dome or cone driver designed to handle high-frequency content, typically above 2,500 Hz to 3,500 Hz, where cone-area efficiency at short wavelengths becomes critical.
- At 1 inch, the tweeter driver produces a relatively narrow, directional high-frequency dispersion pattern, meaning the mounting angle and height within the front door panel directly influence how treble frequencies reach the ear level of seated occupants.
- Mounting a 1 inch tweeter in the front door panel places the high-frequency source lower than the dashboard or A-pillar positions used in some installations, which can affect the perceived soundstage height within the cabin.
- The front door panel location subjects both drivers to mechanical vibration from door operation, window movement, and road noise, conditions that affect driver mounting rigidity and long-term acoustic integrity.
- The simultaneous presence of a 1 inch tweeter and a 6.5 inch midbass or full-range driver in the front door panel indicates a split-driver configuration across the 2008 through 2014 model years covered by the specifications.
