Scion xB Dashboard Speaker Size
The Scion xB dashboard accommodates a 1 inch speaker size across all listed model years. The compatible audio system type for the location is a tweeter. These specifications cover a range from 2004 to 2015.

| 2013 | Tweeter | 1 |
| 2012 | Tweeter | 1 |
| 2011 | Tweeter | 1 |
| 2010 | Tweeter | 1 |
| 2009 | Tweeter | 1 |
| 2008 | Tweeter | 1 |

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. |
Additional Notes
- The dashboard location in the Scion xB accommodates a 1-inch speaker opening across all listed model years.
- Dashboard placement positions speakers at the front of the cabin, near the base of the windshield, which places the sound source at a low height relative to the listening position of occupants.
- The dashboard mounting surface is typically shallow in depth, which limits the physical size of any speaker installed there and explains why a compact 1-inch unit is specified for the Scion xB dashboard.
- A 1-inch driver has a small diaphragm surface area, which allows rapid back-and-forth movement and accurate reproduction of high-frequency sound waves that larger, heavier cones cannot track efficiently.
- The tweeter is the sole compatible type for the Scion xB dashboard location, designating the position as a dedicated high-frequency channel rather than a full-range or mid-bass location.
- Tweeters operate in the upper portion of the audible frequency spectrum, generally handling frequencies above approximately 2,000 Hz, including consonants in speech, string harmonics, and the upper overtones of instruments.
- A 1-inch tweeter in a dashboard position directs high-frequency energy toward the occupant space from a forward angle, as treble wavelengths are short enough to exhibit directional behavior and benefit from front-facing placement.
- Because high frequencies are directional, the dashboard mounting location on the Scion xB places the tweeter in a position where its output can travel toward seated occupants with minimal obstruction from seat structures or door panels.
- The shallow cabinet depth typically associated with dashboard cutouts is acoustically compatible with tweeters, which require minimal enclosure volume compared to woofers or midrange drivers that depend on rear-cavity air space for proper performance.
- A crossover network or head unit signal routing is implied by the tweeter-only designation at the dashboard, as the tweeter requires high-pass filtering to block low-frequency signals that would exceed the mechanical limits of a 1-inch driver.
