Scion iQ Rear Side Panel Speaker Size
The Scion iQ rear side panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio system units. The specifications cover a range of years from 2012 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 |
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 iQ refers to speaker positions integrated into the side panels toward the rear of the cabin, a placement common in compact vehicles where traditional rear door or deck mounting is absent.
- Side panel mounting positions the speaker cone to radiate sound laterally into the cabin rather than directly forward or rearward, which influences how sound interacts with passengers and reflects off interior surfaces.
- The Scion iQ rear side panel accommodates a 6.5 inch speaker across all model years covered in the specifications, representing a mid-sized driver diameter within the passenger car speaker range.
- A 6.5 inch driver produces a cone surface area sufficient to move enough air for meaningful low-to-midrange frequency reproduction, generally covering roughly 60 Hz to 5 kHz depending on the specific speaker's design.
- In a compact vehicle like the Scion iQ, a 6.5 inch driver positioned at the rear side panel contributes to ambient low-frequency fill throughout the small cabin given the limited interior volume.
- Midbass speakers are designed to handle the lower-middle portion of the audible frequency range, typically from around 80 Hz to 500 Hz, emphasizing punch and body in music without extending into high-frequency reproduction.
- When a midbass driver is used at the rear side panel, the lateral orientation and proximity to the vehicle's rear structure can reinforce low-frequency energy through cabin boundary interactions.
- Full-range speakers are designed to reproduce a broader span of frequencies from bass through treble, often incorporating a small whizzer cone or other mechanism to extend high-frequency response from a single driver.
- A full-range driver installed in the Scion iQ rear side panel position handles the entire audible spectrum from a single mounting point, which is relevant in a compact cabin where space for multiple driver types per location may be constrained.
- The 6.5 inch diameter determines the physical cutout and mounting depth requirements at the rear side panel, meaning any compatible replacement speaker must conform to the factory mounting dimensions at that location.
- Mounting depth is a practical constraint at side panel locations because the cavity behind the panel is bounded by the vehicle's body structure, limiting how deep a speaker basket can extend rearward from the mounting surface.
