Lexus GS350 Center Dash Speaker Size
The Lexus GS350 center dash location accommodates a 4 inch speaker size across all listed model years. Compatible types include midrange units suited for the audio system. These specifications cover the 2016 to 2017 model year range.
| 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 GS350 accommodates a 4-inch speaker across the 2016 and 2017 model years.
- A center dash mounting position places the speaker at or near the horizontal centerline of the instrument panel, typically facing upward or toward the windshield, which influences the dispersion angle of sound into the cabin.
- The 4-inch diameter in a center dash position reflects the spatial constraints of the instrument panel cavity, where depth and width are limited by climate control housings, structural supports, and wiring channels.
- A 4-inch driver produces a relatively compact cone area, which limits low-frequency excursion and positions the speaker's usable output range in the upper-bass to upper-midrange frequencies, roughly 200 Hz to 5 kHz depending on the specific driver.
- The midrange type is acoustically defined by a focus on the 500 Hz to 5 kHz band, which contains the fundamental frequencies of the human voice and the presence region of most musical instruments.
- A midrange driver in the center dash of the Lexus GS350 supports front-stage imaging by placing voice-range frequencies at a central point between the left and right channels, reinforcing the perceived center of the soundstage.
- Midrange drivers are generally built with cone geometries and surround materials optimized for controlled pistonic motion across the vocal frequency band, rather than the high-excursion behavior required of woofers or the stiff, lightweight diaphragms used in tweeters.
- The 4-inch form factor in a midrange application means the driver is not expected to reproduce deep bass, and the center dash location in the GS350 is consistent with a system architecture that delegates low-frequency reproduction to separate speakers elsewhere in the vehicle.
