Lexus RX350 Rear Door Panel Speaker Size
The Lexus RX350 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio units, which represent the supported speaker categories within the system. These specifications cover the 2007 to 2015 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | 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 RX350 rear door panel is a surface-mounted speaker location integrated into the interior door trim, positioning the driver at a low and lateral point relative to the listening area.
- Door panel mounting places the speaker within a sealed or partially sealed cavity formed by the door's inner structure, which affects low-frequency loading and the speaker's effective acoustic output.
- The rear door panel location situates the speaker behind and beside rear passengers, contributing ambient fill and spatial width to the overall soundstage rather than direct front-facing output.
- A 6.5 inch speaker occupies a mid-sized cone area that balances low-frequency extension with the physical constraints of a door panel cutout, making the format common for door-mounted applications where depth and width are limited.
- The cone diameter of 6.5 inches supports a frequency range that typically spans from the upper bass region into the lower midrange, which aligns with the rear door's acoustic role of reinforcing warmth and body in the rear cabin.
- A midbass driver is a dedicated transducer designed to reproduce the frequency band roughly between 80 Hz and 500 Hz, handling punch and low-midrange weight without extending into high frequencies.
- In a rear door panel position, a midbass driver reinforces the low-frequency content experienced by rear passengers and contributes to overall bass distribution throughout the cabin when crossed over within a multi-way system.
- A full-range driver is designed to reproduce a wider frequency span across bass, midrange, and portions of the treble, functioning as the sole transducer at a given location without requiring additional high-frequency support.
- When a full-range driver occupies the rear door panel position in the Lexus RX350, the 6.5 inch cone handles the full audio spectrum for that mounting location, including midrange vocal reproduction for rear-seat passengers.
- The compatibility of both midbass and full-range types within the same 6.5 inch cutout indicates the mounting dimensions are consistent across both driver configurations for the rear door panel of the RX350 across the 2007 through 2015 model range.
