Lexus GS200t Center Dash Speaker Size
The Lexus GS200t center dash location accommodates a 4 inch speaker size. Compatible types include midrange audio units suited for the system. 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 GS200t positions a speaker at the upper central point of the instrument panel, a placement that favors forward sound projection toward the listening area of the cabin.
- A 4-inch driver in the center dash occupies a compact footprint, consistent with the spatial constraints typical of instrument panel cavities, where depth and diameter are limited by underlying HVAC and structural components.
- The center dash position places the speaker closer to ear level than door-mounted locations, which affects the perceived directionality and imaging of frequencies reproduced at that point.
- A 4-inch cone diameter produces a relatively small radiating surface area, which relates directly to the upper-midrange and midrange frequency bands the driver is expected to handle in this installation.
- The midrange type is designated for the Lexus GS200t center dash across both the 2016 and 2017 model years, meaning the driver in this location is responsible for reproducing the core vocal and instrumental frequencies, generally spanning approximately 300 Hz to 5 kHz.
- Midrange drivers are acoustically suited for center dash placement because the frequencies they reproduce are highly sensitive to localization by human hearing, and a centrally mounted source supports stable stereo imaging between left and right channels.
- The 4-inch size at a midrange-specific installation point means the driver is not expected to extend into deep bass reproduction, which would require significantly greater cone area and excursion capability than a 4-inch format allows.
- Midrange drivers typically use a relatively stiff, lightly dampened cone construction to maintain accurate transient response across the frequency band where speech intelligibility and tonal clarity are concentrated.
- The center dash mounting surface in the GS200t is a fixed, rigid panel, which affects the acoustic coupling between the speaker basket and the surrounding structure, influencing resonance behavior at the installation point.
- Because the center dash location is equidistant from both the driver and front passenger seating positions, a midrange driver placed there produces a shared phantom center image rather than a stereo-split signal.
