Acura RLX Rear Door Panel Speaker Size
The Acura RLX rear door panel accommodates a 1 inch speaker size and 6.5 inch speakers across all listed model years. Compatible types for the audio system include tweeters and midbass or full-range units. These specifications cover the 2014 to 2017 model year range.
| 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 rear door panel accommodates 2 distinct speaker sizes simultaneously: 1 inch and 6.5 inch, indicating a multi-driver configuration within the door cavity.
- Door panel speaker locations are typically recessed within a mounting baffle or grille assembly, with the door skin and interior trim acting as an enclosure that influences bass response and midrange coloration.
- The 6.5 inch diameter is a standard mid-woofer size whose cone surface area generates sufficient air displacement to reproduce lower frequencies, making the rear door panel an effective location for bass and lower midrange energy within the cabin.
- A 6.5 inch driver in a rear door panel position operates within a partially sealed cavity formed by the door shell, which can augment low-frequency output without a dedicated subwoofer enclosure.
- The midbass designation for the 6.5 inch driver indicates a frequency focus generally spanning from the upper bass region into the lower midrange, prioritizing punch and warmth over full high-frequency extension.
- When configured as full-range, the 6.5 inch driver in the Acura RLX rear door panel covers a broader spectrum from bass through upper midrange, operating without a passive crossover to a separate high-frequency driver in the same location.
- The 1 inch tweeter size produces short, lightweight cone or dome excursions suited to high-frequency reproduction, typically handling content above 2,000 to 3,500 Hz where larger drivers lose accuracy due to cone breakup and beaming.
- Tweeters are highly directional at high frequencies, and placement within the rear door panel positions the 1 inch driver toward the vehicle's lower cabin zone, which affects the perceived high-frequency staging from rear seating positions.
- The pairing of a 1 inch tweeter alongside a 6.5 inch midbass or full-range driver in the rear door panel reflects a 2-way speaker arrangement, where the two drivers divide the audible frequency range between them at the installation location.
- Rear door panel mounting depth and baffle diameter constraints directly determine the maximum driver dimensions that physically fit, and the 6.5 inch specification represents the largest diameter compatible with the RLX rear door panel opening across the 2014 through 2017 model years.
