Lexus GS350 Rear Door Panel Speaker Size
The Lexus GS350 rear door panel accommodates 6.5 inch speakers and supports a 6.75 inch speaker size across its model range. Compatible audio types for both units include midbass and full-range. These specifications cover the 2007 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.75 |
| 2016 | Midbass / Full-Range | 6.75 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The Lexus GS350 rear door panel locations house speakers within the door structure itself, meaning the mounting depth and baffle surface are determined by the inner door cavity and panel cutout dimensions.
- A 6.75 inch speaker occupies a slightly larger cone area than a 6.5 inch unit, which increases the moving mass available for low-to-mid frequency reproduction in the rear door position.
- A 6.5 inch speaker is a widely standardized mid-woofer diameter, with a cone area suited to reproducing frequencies roughly between 60 Hz and 5 kHz, depending on driver construction and crossover configuration.
- Rear door panel locations place speakers at a lower height within the cabin, which positions the sound source closer to the floor and further from the listener's ear level compared to front door or dashboard locations.
- The midbass type is a driver optimized for the lower portion of the midrange and upper bass frequencies, typically covering approximately 80 Hz to 500 Hz, and is commonly used in systems where a separate tweeter handles higher frequencies.
- The full-range type is a single driver designed to reproduce a broad spectrum of frequencies without requiring a dedicated tweeter, making the Lexus GS350 rear door panel location compatible with both single-driver and multi-driver system configurations.
- Door panel mounting subjects the speaker basket to the mechanical vibrations of the door structure, which can affect resonance behavior at the lower frequencies that midbass and full-range drivers in a 6.5 or 6.75 inch format are most likely to reproduce.
- The rear door position in a sedan cabin creates a physical distance between the speaker and the front-seat listener, which influences the perceived stereo imaging and the time-arrival relationship of rear-sourced sound relative to front speakers.
- A 6.75 inch driver requires a mounting cutout diameter larger than a 6.5 inch driver, meaning the rear door panel of 2016 and 2017 GS350 models accommodates a physically wider opening than the panels found in earlier model years listed in the specifications.
- Full-range drivers in a rear door panel location are responsible for reproducing the complete audible spectrum from a single cone, which demands a broader excursion range and more complex cone geometry than a dedicated midbass driver of the same diameter.
- The rear door panel on a sedan model such as the GS350 typically provides a semi-enclosed air volume behind the speaker basket formed by the door's inner and outer metal skins, which acts as a partial acoustic chamber influencing bass response.
