Scion tC Rear Side Panel Speaker Size
The Scion tC rear side panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the audio system include midbass and full-range units. The specifications cover a range of years from 2005 to 2016.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Midbass / Full-Range | 6.5 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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 rear side panel location in the Scion tC accepts a 6.5 inch speaker across all listed model years.
- Side panel mounting positions in vehicles are typically recessed within a trim cavity, orienting the speaker cone toward the cabin interior at an angle determined by the panel's contour.
- A 6.5 inch diameter cone provides a radiating surface area large enough to move the air volume needed to reproduce lower midrange and upper bass frequencies effectively within an enclosed cabin space.
- The rear side panel location places the speaker behind the primary seating area, meaning the driver and front passengers receive reflected or indirect sound from this position rather than direct on-axis output.
- A 6.5 inch driver in a side panel enclosure is bounded by the panel cavity depth and internal volume, both of which influence the low-frequency extension the driver can achieve in practice.
- Midbass drivers are designed to handle frequencies roughly between 80 Hz and 500 Hz, concentrating acoustic energy in the range where bass punch and lower vocal body are perceived.
- When a midbass driver is installed in the Scion tC rear side panel, the location functions as a bass reinforcement point, supporting low-frequency output that complements higher-frequency sources positioned elsewhere in the cabin.
- Full-range drivers are designed to reproduce a wider frequency span, typically from around 60 Hz up to 20 kHz, using a single cone and sometimes an integrated whizzer cone for high-frequency extension.
- A full-range driver installed in the rear side panel of the Scion tC allows the position to serve as a standalone acoustic source, reproducing bass, midrange, and treble without requiring a separate tweeter at that location.
- The 6.5 inch format is a standard automotive speaker size, meaning mounting hole patterns, depth tolerances, and frame diameters align with common aftermarket speaker specifications designed for typical factory cutout dimensions.
- Side panel locations generally lack the rigid, sealed baffle conditions associated with dedicated enclosures, so the panel cavity behind a 6.5 inch driver may allow some bass leakage or acoustic coupling with the rear interior structure.
