Acura RSX Rear Side Panel Speaker Size
The Acura RSX rear side panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio system units. These specifications cover the 2002 to 2006 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | Midbass / Full-Range | 6.5 |
| 2003 | Midbass / Full-Range | 6.5 |
| 2002 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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 RSX rear side panel location accepts 6.5 inch speakers across all listed model years from 2002 through 2006.
- Rear side panel locations in compact coupes such as the RSX are typically recessed into the lower rear quarter interior trim, positioning drivers closer to the floor and angled toward the cabin rather than facing directly at seated occupants.
- A 6.5 inch driver occupies a diameter range that supports meaningful cone surface area for moving air at lower frequencies, making the size well suited to a rear side panel location where low-frequency reinforcement and spatial fill are primary acoustic functions.
- The 6.5 inch cone diameter also allows for sufficient excursion depth to reproduce the lower portion of the midrange spectrum with adequate output, which benefits rear-fill performance in a compact cabin.
- Midbass drivers are designed to reproduce the frequency band roughly between 80 Hz and 500 Hz, covering the lower midrange and upper bass registers that contribute to warmth and body in musical reproduction.
- In a rear side panel position, a midbass driver at 6.5 inches contributes low-frequency energy that supplements a front soundstage, adding weight and presence without requiring a dedicated subwoofer enclosure in the cargo area.
- Full-range drivers are designed to reproduce a wide frequency band from bass through treble within a single driver, typically spanning from approximately 60 Hz to 20 kHz, allowing a single speaker to handle the entire audible spectrum at a given location.
- When a full-range type is installed in the Acura RSX rear side panel position, the driver handles all frequencies independently at that location, which is a common configuration in factory or simplified aftermarket audio systems where no dedicated tweeters are present in the rear.
- The rear side panel mounting location in a coupe body style tends to place drivers at a relatively low height within the cabin, which affects the directional dispersion of higher frequencies, as high-frequency sound from a full-range driver at that position may be partially absorbed or reflected by seating and interior materials before reaching occupants.
- The compatibility of both midbass and full-range types at the same 6.5 inch size in the RSX rear side panel indicates the location accommodates either a crossed-over driver in a multi-component system or a standalone full-range driver depending on the system configuration used.
