| 2006 | Tweeter | 1 |
| 2005 | Tweeter | 1 |
| 2004 | Tweeter | 1 |
| 2003 | Tweeter | 1 |
| 2002 | Tweeter | 1 |
| 2001 | Tweeter | 1 |
| 2000 | Tweeter | 1 |
| 1999 | Tweeter | 1 |
| 1998 | Tweeter | 1 |
| 1997 | 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 speaker location in the Infiniti Q45 accommodates a 1-inch driver across the 1997 through 2006 model years.
- A 1-inch tweeter is a compact, high-frequency transducer typically reproducing sounds in the upper range of the audible spectrum, generally from around 2 kHz to 20 kHz.
- Dashboard placement positions tweeters at ear level and near the front of the listening environment, which supports accurate imaging of high-frequency content across the vehicle cabin.
- The small diaphragm area of a 1-inch tweeter allows for rapid movement with minimal mass, which is mechanically suited to reproducing short, fast wavelengths characteristic of high-frequency audio content.
- Tweeters are directional by nature, and the dashboard location in the Infiniti Q45 places the drivers in a position angled toward the occupants, which is consistent with high-frequency dispersion requirements.
- The dashboard environment involves hard, shallow mounting surfaces, and a 1-inch tweeter has a shallow mounting depth relative to larger driver types, making the form factor mechanically compatible with such spatial constraints.
- Because tweeters do not reproduce bass or midrange frequencies, the dashboard location in the Q45 functions exclusively within the high-frequency portion of a multi-speaker audio system.
- The 1-inch diaphragm size is a common dimension in automotive tweeters and corresponds to a compact mounting cutout, which suits the limited real estate typically available in dashboard panels.
