Infiniti G20 A-Pillar Speaker Size
The Infiniti G20 A-Pillar accommodates a 1 inch speaker size across all listed model years. Tweeter units are the compatible audio replacement type for the system. These specifications cover the years 1999 to 2002.
| Year | Type | Size (inch) |
|---|---|---|
| 2002 | Tweeter | 1 |
| 2001 | Tweeter | 1 |
| 2000 | Tweeter | 1 |
| 1999 | 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 A-pillar location in the Infiniti G20 accommodates a 1-inch speaker across the 1999 through 2002 model years.
- A-pillar mounting positions speakers at the forward upper corners of the cabin interior, near the windshield and at ear level when seated, placing sound sources at the front of the listening field.
- The 1-inch diameter specifies a physically small driver, which is consistent with high-frequency reproduction where a small radiating surface allows the cone or dome to move rapidly without the mass penalty that would reduce treble output.
- The tweeter is the sole compatible type listed for the A-pillar position in the Infiniti G20, meaning only high-frequency drivers are specified for this location.
- Tweeters handle the upper portion of the audible frequency spectrum, typically covering frequencies above approximately 2,000 Hz, where wavelengths are short enough to be directed and focused by small surfaces.
- Placement at the A-pillar positions the tweeter at a forward angle toward the listening area, which is relevant because high-frequency sound is directional and its perceived clarity depends on the driver being aimed toward the listener.
- The 1-inch form factor in an A-pillar installation means the mounting cavity in the pillar trim is sized to a narrow profile, as A-pillar housings are structurally constrained by the pillar's role in the vehicle body frame.
- Because tweeters reproduce frequencies with short wavelengths, a 1-inch driver at the A-pillar position contributes to stereo imaging by giving the auditory impression that sound originates from a point in front of and above the listener rather than from lower door-mounted speakers.
