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 deck lid of the BMW 760Li is a horizontal panel positioned at the rearmost interior-facing surface of the trunk, placing speakers at the back of the cabin where sound projects forward toward the passenger compartment.
- The deck lid location positions speakers at a relatively low height relative to seated ear level, which influences how high-frequency directional content from tweeters reaches rear and front occupants.
- A 4 inch midrange driver in a deck lid mounting location handles the vocal and instrumental frequency band, generally spanning roughly 300 Hz to 5 kHz, filling the mid-cabin with tonal content from behind the rear passengers.
- The compact diameter of the 4 inch midrange driver limits low-frequency extension, making the deck lid position a supplementary mid-frequency source rather than a full-range one.
- The 1 inch tweeter size, present in model years 2010 through 2015, is a standard small-dome format suited to reproducing high frequencies typically above 2 kHz, where wavelengths are short enough that the 1 inch diaphragm can radiate efficiently without significant beaming.
- The 0.75 inch tweeter size, present in model years 2003 through 2008, has an even smaller diaphragm than the 1 inch variant, which can allow for a slightly higher crossover point and reduced low-frequency excursion capacity at the same drive level.
- Tweeters are highly directional at the upper end of their operating range, so the deck lid mounting angle and baffle geometry of the BMW 760Li rear deck lid directly affect the dispersion of high-frequency content toward occupants.
- The pairing of a tweeter and a midrange driver at the same location indicates a two-way speaker arrangement at the rear deck lid, dividing the audible frequency spectrum between the 2 drivers rather than relying on a single full-range unit.
- The BMW 760Li rear deck lid accommodates 2 distinct speaker diameters simultaneously, requiring the panel to have separate mounting cutouts sized for the 4 inch midrange and the respective tweeter diameter.
- The 0.75 inch tweeter used in model years 2003 through 2008 is among the smaller dome sizes in consumer audio, and the transition to a 1 inch tweeter in model year 2010 represents a shift to a larger diaphragm at the same rear deck lid mounting position.
- Midrange drivers in a deck lid position radiate into the rear cabin volume first, with the sound then traveling forward through the interior, affecting tonal balance differently for rear-seat versus front-seat occupants.
