BMW M760i xDrive Rear Door Panel Speaker Size
The BMW M760i xDrive rear door panel accommodates a 1 inch speaker size and 4 inch speakers. Compatible types for these units include tweeters and midrange speakers. These specifications cover the 2017 to 2018 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2018 | Midrange | 4 |
| 2017 | Tweeter | 1 |
| 2017 | Midrange | 4 |
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. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear door panel location on the BMW M760i xDrive accommodates 2 distinct speaker sizes, 1 inch and 4 inch, each serving a separate acoustic function within the same installation zone.
- A 1-inch tweeter operates in the upper frequency range, typically reproducing sounds above 2,000 Hz, where short wavelengths require a small driver to maintain accuracy and dispersion without distortion.
- The rear door panel position places the 1-inch tweeter at a relatively low height within the cabin, which influences the angle and projection of high-frequency content toward rear seat passengers.
- A 4-inch midrange driver handles the middle portion of the audible frequency spectrum, generally spanning from approximately 300 Hz to 5,000 Hz, where vocal clarity and instrument body are most prominent.
- The rear door panel mounting surface typically orients a 4-inch midrange driver to project sound laterally into the cabin, affecting the stereo image perceived by rear occupants.
- Door panel installations are subject to panel resonance and cavity volume behind the driver, both of which interact with a 4-inch midrange speaker's low-frequency extension and overall output character.
- The 1-inch tweeter in the BMW M760i xDrive rear door panel requires a crossover point that prevents low-frequency content from reaching the small driver, as high excursion at low frequencies can damage a tweeter of that diameter.
- The spatial separation between the 1-inch tweeter and the 4-inch midrange within the same door panel creates a two-way configuration at the rear door, where crossover alignment between the 2 drivers affects tonal coherence for rear seat listeners.
