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 center dash location in the BMW 760Li places speakers at the forward-most point of the cabin interior, along the horizontal surface where the dashboard meets the windshield, positioning drivers directly in the acoustic projection path toward front occupants.
- A center dash mounting position is typically shallow in depth, which constrains the physical profile of compatible speakers and favors compact driver configurations such as those sized at 1 inch and 4 inches.
- The 4 inch midrange driver specified for the BMW 760Li center dash across the 2003-2015 model range handles the mid-frequency band, generally covering approximately 300 Hz to 5,000 Hz, which encompasses vocals, instruments, and the primary body of most audio content.
- At the center dash location, a 4 inch midrange driver projects sound forward and upward toward the windshield plane, contributing to a centered stereo image perceived between the front seats.
- The 4 inch cone diameter provides sufficient surface area to move air for mid-frequency reproduction without requiring the enclosure depth that larger drivers demand, making the format well-suited to the limited vertical clearance of a dashboard cavity.
- The 1 inch tweeter specified for the BMW 760Li center dash in model years 2010 through 2015 handles high-frequency content, generally from approximately 2,000 Hz to 20,000 Hz, restoring upper harmonic detail, consonants in speech, and transient sounds such as cymbals.
- A 1 inch tweeter dome, the standard form associated with tweeters of the size listed in the specifications, radiates high frequencies with wide dispersion across a broad listening area, which at the center dash position distributes treble evenly across both front seating positions.
- High frequencies are highly directional, and the center dash mounting point places the 1 inch tweeter on-axis relative to front occupants, reinforcing treble presence without the off-axis attenuation that would affect a tweeter mounted at a lower or more lateral position.
- The pairing of a 1 inch tweeter with a 4 inch midrange at the center dash location in the 2010-2015 BMW 760Li creates a two-driver array in a single installation zone, requiring crossover management to divide frequency responsibilities between the 2 drivers.
- The 2003-2008 model years of the BMW 760Li carry only the 4 inch midrange specification for the center dash, without a corresponding 1 inch tweeter entry for the same location.
