Lexus CT200h Rear Door Panel Speaker Size
The Lexus CT200h rear door panel accommodates a 6.75 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio system units. These specifications cover the 2011 to 2015 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | Midbass / Full-Range | 6.75 |
| 2014 | Midbass / Full-Range | 6.75 |
| 2013 | Midbass / Full-Range | 6.75 |
| 2012 | Midbass / Full-Range | 6.75 |
| 2011 | Midbass / Full-Range | 6.75 |
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 CT200h rear door panel location houses speakers within the door's inner panel cavity, where the speaker cone faces into the cabin and relies on the door's internal air volume as a rear acoustic chamber.
- A 6.75-inch driver occupies a mid-to-large diameter range for automotive door installations, producing a cone area large enough to move sufficient air for lower midrange and upper bass frequencies in a door panel environment.
- The rear door panel position places speakers farther from the primary listening area than front doors, which affects the time-alignment contribution of rear-mounted drivers within a full cabin soundstage.
- Door panel locations are subject to road vibration and moisture exposure from window seals, which are mechanical factors that influence driver surround material selection and basket rigidity requirements for the 6.75-inch aperture.
- A 6.75-inch mounting cutout requires the installer to verify both the outer diameter and mounting depth against the door's inner panel clearance, as rear door cavities on the CT200h have fixed depth constraints behind the panel skin.
- The midbass type, listed as compatible for the Lexus CT200h rear door panel, is a driver optimized for the frequency range approximately between 80 Hz and 500 Hz, reinforcing lower vocal fundamentals and the body of bass-heavy instruments without extending into treble reproduction.
- A midbass driver in the rear door location functions as a bass-support element in a multi-component audio system, typically crossed over from a dedicated subwoofer below and handed off to a midrange or tweeter above.
- The full-range type, also listed as compatible for the rear door panel position, is designed to reproduce a wide frequency span from low bass through high treble without an external crossover, making the single driver responsible for the entire audible spectrum at that location.
- Full-range drivers at 6.75 inches in a door panel tend to exhibit wider horizontal dispersion in the midrange frequencies, which can influence how evenly sound distributes across rear seating positions in the CT200h cabin.
- The rear door panel location, as opposed to a rear deck or rear pillar position, allows the speaker to project sound forward along the cabin floor plane rather than downward or rearward, affecting the directional contribution to overall cabin acoustics.
