Lexus ES350 Center Dash Speaker Size
The Lexus ES350 center dash location accommodates a 4 inch speaker size. Compatible types for the center dash include midrange units. These specifications cover the 2016 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midrange | 4 |
| 2016 | Midrange | 4 |
Speaker Types
| Type | Description |
|---|---|
| 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 Lexus ES350 is a surface-mounted position integrated into the upper dashboard panel, placing speakers at a central, forward-facing angle directed toward the vehicle's cabin.
- A center dash position situates speakers at a relatively shallow mounting depth, which typically requires compact driver dimensions to fit within the dashboard's internal clearance.
- The 4-inch diameter specified for the Lexus ES350 center dash corresponds to a small-format driver size suited to the limited physical space available within a dashboard cavity.
- A 4-inch driver produces a relatively narrow cone surface area, which affects cone excursion and limits low-frequency extension compared to larger drivers in more spacious mounting locations.
- The center dash placement positions the speaker equidistant from the left and right seating positions, a location acoustically significant for anchoring sound to the center of the stereo or surround field.
- Midrange drivers are designed to reproduce frequencies approximately between 300 Hz and 5,000 Hz, covering the core band of vocal intelligibility and a substantial portion of instrumental fundamentals.
- The midrange type specified for the Lexus ES350 center dash aligns with the acoustic demands of a centrally located speaker, where clarity of voice and dialogue reproduction is a primary functional priority.
- A 4-inch midrange driver in a center dash position operates within a frequency band where directional sound localization by human hearing is most acute, making placement accuracy at the center axis acoustically relevant.
- Midrange drivers are typically not designed to handle the full frequency spectrum independently and function within a multi-speaker system where lower and higher frequencies are managed by separate drivers elsewhere in the vehicle.
- The 4-inch format is mechanically compatible with the torque and excursion requirements of a midrange-only driver, as midrange reproduction demands less cone movement than woofer-range reproduction.
