Acura RLX Front Door Panel Speaker Size
The Acura RLX front door panel accommodates a 1 inch speaker size and 6.5 inch speakers. Compatible types across all positions include tweeters and midbass or full-range units. The specifications cover the 2014 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Tweeter | 1 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Tweeter | 1 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Tweeter | 1 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Tweeter | 1 |
| 2014 | 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 Acura RLX front door panel accommodates 2 distinct speaker sizes simultaneously, with a 1-inch position and a 6.5-inch position present across all listed model years.
- Front door panels are a structurally rigid mounting surface that integrates speakers directly into the cabin at roughly ear level for seated occupants, placing the sound source in close proximity to the listening position.
- The 6.5-inch diameter is a widely used mid-size driver format in automotive door installations, where the door cavity provides the enclosed air volume that supports low-frequency extension in a midbass or full-range role.
- A 6.5-inch driver in a front door panel handles the lower and middle portions of the audible frequency spectrum, typically covering roughly 60 Hz to 5 kHz depending on crossover configuration, which accounts for the fundamental tones of most musical instruments and vocals.
- The midbass designation for the 6.5-inch position indicates a driver focused on the lower-midrange and upper-bass frequencies, generally operating below a crossover point where a separate tweeter takes over the high-frequency reproduction.
- The full-range designation for the 6.5-inch position indicates a driver capable of reproducing a broad frequency span without requiring a dedicated crossover network, spanning bass through high-midrange content independently.
- The 1-inch tweeter size is a compact high-frequency driver whose small diaphragm mass allows rapid pistonic movement, enabling reproduction of frequencies typically above 2 kHz to 3 kHz where larger drivers begin to lose controlled directional behavior.
- Tweeters mounted in front door panels are positioned to direct high-frequency content toward the cabin listening area, as high frequencies are highly directional and require deliberate angular placement to maintain stereo imaging and tonal balance.
- The 1-inch tweeter format is among the most common automotive tweeter diameters, often fitted into dedicated pods or recesses within the upper section of a door panel to optimize the dispersion angle toward the occupant.
- The coexistence of a 1-inch tweeter and a 6.5-inch midbass or full-range driver in the same front door panel indicates a 2-way speaker arrangement within a single door location, where the 2 drivers divide the frequency spectrum between them.
