Mercedes-Benz R500 Rear Door Panel Speaker Size
The Mercedes-Benz R500 rear door panel accommodates a 6.5 inch speaker size and supports 1 inch units. Compatible speaker types for the location include midbass, full-range, and tweeter. These specifications cover the 2006 to 2007 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2007 | Midbass / Full-Range | 6.5 |
| 2007 | Tweeter | 1 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2006 | 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. |
| 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 on the Mercedes-Benz R500 accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver mounting configuration within the door panel structure for both the 2006 and 2007 model years.
- Door panel installations are typically surface-mounted or recessed into a molded cavity within the interior door trim, with the panel itself acting as the baffle that influences low-frequency response and overall acoustic projection into the cabin.
- The 6.5-inch mounting position in the rear door panel places a mid-to-large diameter driver at a lower position within the cabin, angled toward the passenger seating area, which affects the dispersion pattern and bass reinforcement characteristics at that listening position.
- A 6.5-inch driver carries sufficient cone surface area to reproduce frequencies from the upper bass range through the midrange, generally spanning approximately 60 Hz to 5 kHz depending on the driver's design, making the rear door panel a mechanically appropriate location for low-frequency reinforcement in the rear seating zone.
- The midbass designation for the 6.5-inch position indicates operation focused on the lower portion of the midrange and upper bass frequencies, typically 80 Hz to 500 Hz, where the rear door panel's proximity to the floor and door structure supports bass coupling to the cabin interior.
- The full-range designation as an alternative compatible type for the 6.5-inch position means a single driver at that location can handle frequencies spanning bass through treble without a dedicated tweeter operating alongside it in the same zone.
- The Mercedes-Benz R500 rear door panel also carries a dedicated 1-inch mounting position, which is sized for high-frequency reproduction above the range where a 6.5-inch driver begins to exhibit beaming or roll-off.
- A 1-inch tweeter operates in the upper frequency range, typically from approximately 2 kHz to 20 kHz, and the rear door panel placement positions high-frequency dispersion toward rear-seat occupants at a height determined by the panel's structural layout.
- Tweeters in door panel locations rely on wide dispersion characteristics to distribute high-frequency content across the rear seating positions, as 1-inch dome or cone tweeters generally exhibit broader directional coverage than larger drivers at equivalent frequencies.
- The simultaneous presence of a 6.5-inch midbass/full-range position and a 1-inch tweeter position within the same rear door panel indicates the panel has physically separated mounting cutouts or housings for each driver size.
