BMW 740Le xDrive Center Dash Speaker Size
The BMW 740Le xDrive center dash location accommodates a 1 inch speaker size and 4 inch speakers. Compatible types for these units include tweeter and midrange audio components within the system. These specifications cover the 2017 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 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 center dash location in the 2017 BMW 740Le xDrive accommodates 2 distinct speaker sizes, a 1 inch and a 4 inch, each assigned to a different driver type.
- A 1 inch tweeter operates in high-frequency ranges, typically covering approximately 2 kHz and above, where short wavelengths require a small, precise diaphragm to reproduce treble detail accurately at the center dash position.
- Placement of a tweeter at the center dash positions high-frequency sound reproduction at a central point along the front of the cabin, contributing to a focused stereo image between the driver and front passenger.
- The 4 inch driver at the center dash position is designated as a midrange type, responsible for frequencies roughly between 300 Hz and 5 kHz, which encompasses much of vocal and instrumental presence in audio content.
- A 4 inch cone diameter provides sufficient surface area for midrange reproduction while remaining physically compact enough to fit within the constrained depth and width typical of a center dash enclosure.
- The BMW 740Le xDrive center dash location houses both a tweeter and a midrange driver, indicating a multi-driver configuration within a single installation zone rather than a single full-range unit.
- Midrange drivers of 4 inches are sensitive to enclosure volume and baffle conditions; the shallow cavity behind a center dash panel directly influences the loading characteristics of the cone at lower midrange frequencies.
- The 1 inch tweeter designation in the 2017 BMW 740Le xDrive center dash confirms a dome or similarly compact high-frequency transducer sized to fit within the spatial constraints of a recessed dash housing.
