Acura RSX Rear Door Panel Speaker Size
The Acura RSX rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. These specifications cover the 2006 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | 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 rear door panel location in the 2006 Acura RSX accommodates a 6.5-inch speaker cutout, a mid-size diameter common to door mounting applications where cone surface area and enclosure depth must be balanced against the limited cavity behind the door skin.
- Door panel installations are typically surface-mounted or recessed into a molded pocket within the door, with the speaker basket seated against a mounting ring or factory bracket and secured at the perimeter.
- The depth of the door cavity behind the mounting surface is a critical spatial factor in rear door installations, as the speaker's magnet and basket must clear interior metal bracing, window regulator mechanisms, and wiring runs within the door shell.
- A 6.5-inch driver in a rear door location operates within a semi-enclosed acoustic space formed by the door cavity itself, which functions as an unintentional enclosure that can influence low-frequency output and resonance behavior.
- The 6.5-inch diameter provides a cone area capable of moving sufficient air for upper bass and lower midrange reproduction, with a typical usable frequency range spanning roughly 60 Hz to 5 kHz depending on driver design.
- The midbass type, listed as compatible for the Acura RSX rear door panel, is a driver optimized for the lower portion of the midrange and upper bass frequencies, generally operating below 500 Hz and crossed over from higher-frequency drivers in a multi-speaker system.
- A midbass driver in a rear door location is typically paired with a dedicated tweeter elsewhere in the vehicle to maintain full-spectrum coverage, as the driver's roll-off above the midrange leaves upper frequencies unreproduced.
- The full-range type, also listed as compatible, is designed to reproduce a wider frequency span within a single driver, covering bass, midrange, and a portion of the high frequencies without requiring a separate tweeter for basic stereo operation.
- In a rear door mounting position, full-range drivers benefit from the lateral placement relative to the listening position, which affects stereo imaging and the perceived directionality of mid and high frequencies reaching the rear seating area.
- The rear door panel position places the speaker at approximately seat-height level, directing sound horizontally across the cabin floor rather than vertically toward the headliner, a geometry that influences how high-frequency content disperses through the interior.
