Scion xB Rear Side Panel Speaker Size
The Scion xB rear side panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. These specifications cover the years 2004 to 2015.
| Year | Type | Size (inch) |
|---|---|---|
| 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 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | 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 xB places speakers within the interior side walls toward the rear of the cabin, a position generally angled toward occupants rather than firing directly forward.
- Side panel mounting positions the speaker cone along a lateral plane, which affects soundstage width and rear-cabin fill relative to forward-facing door or dash placements.
- The 6.5 inch diameter is the sole speaker size across all model years listed in the specifications, making a single mounting cutout dimension and depth clearance consistent across the entire production range covered.
- A 6.5 inch speaker carries a cone area sufficient to reproduce bass and lower midrange frequencies with meaningful displacement, making the size acoustically appropriate for a rear side panel location where low-frequency reinforcement is a common role.
- The physical depth and baffle requirements of a 6.5 inch driver mean that adequate mounting depth behind the side panel surface is necessary to avoid mechanical interference with the vehicle interior structure.
- Midbass is one of the 2 compatible types specified for the Scion xB rear side panel, and a midbass driver is designed to handle the lower portion of the midrange and upper bass frequencies, roughly from around 80 Hz to 500 Hz, without attempting to reproduce high frequencies.
- In a rear side panel application, a midbass driver concentrates acoustic energy on foundational frequencies that contribute to perceived weight and body in music reproduction within the cabin.
- Full-range is the second compatible type specified, and a full-range driver is engineered to reproduce a wider frequency band spanning bass, midrange, and portions of treble from a single cone.
- A full-range driver installed in the rear side panel position of the Scion xB would handle the entire audible spectrum assigned to that location without requiring a separate tweeter in the same position.
- The rear side panel location, relative to front seating positions, places the speaker at a greater distance from the front occupants, which influences time alignment and the perceived directionality of higher frequencies reproduced by a full-range driver in that position.
- Both compatible types share the same 6.5 inch mounting requirement, meaning the physical installation parameters remain identical regardless of which type is selected.
