Scion iQ Front Door Panel Speaker Size
The Scion iQ front door panel accommodates a 1 inch speaker size and 6.5 inch speakers. Compatible audio types for these locations include tweeters and midbass or full-range units. The specifications cover a system of years ranging from 2012 to 2015.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 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 |
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 iQ front door panel accommodates 2 distinct speaker sizes simultaneously, with a 1-inch position and a 6.5-inch position occupying the same door panel location across all listed model years.
- Door panel installations are typically surface-mounted or flush-mounted within the door's inner cavity, with the panel itself acting as the baffle that affects resonance and low-frequency output of any mounted driver.
- The 6.5-inch mounting position in the Scion iQ front door panel is sized to seat a driver with a relatively wide cone area, which in a door cavity supports the reproduction of lower-mid and upper-bass frequencies through physical cone displacement.
- A 6.5-inch driver in a door panel location benefits from the door cavity volume acting as a partial enclosure, which can reinforce bass extension below the driver's free-air resonance point.
- The midbass type compatible with the 6.5-inch position is a driver optimized for the frequency band roughly between 80 Hz and 500 Hz, handling the punch and body of bass and lower midrange without attempting to reproduce high frequencies.
- The full-range type compatible with the 6.5-inch position is a driver designed to reproduce a wide portion of the audible spectrum from bass through treble, relying on a single cone or a cone with an integrated whizzer to cover multiple frequency bands from 1 mounting point.
- The 1-inch mounting position in the front door panel is sized for a small, lightweight driver whose reduced diaphragm mass allows rapid movement at high frequencies, making the position acoustically suited to treble reproduction.
- In a front door panel, a 1-inch tweeter placement positions the high-frequency driver at a low height relative to the listener, which affects the perceived stereo imaging and high-frequency directionality within the cabin.
- The tweeter type compatible with the 1-inch position in the Scion iQ front door panel reproduces frequencies generally above 2 kHz, a range where wavelengths are short enough that driver size and placement angle have a measurable effect on tonal balance at the listening position.
- The presence of both a 1-inch tweeter position and a 6.5-inch midbass/full-range position in the same door panel indicates a layout capable of supporting a 2-way component speaker system, where the frequency spectrum is divided between the 2 separate drivers.
