Cadillac ATS Rear Door Panel Speaker Size
The Cadillac ATS 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 speakers. These specifications cover the 2013 to 2016 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | 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 rear door panel location in the Cadillac ATS positions speakers within the lower portion of the door cavity, where mounting depth and baffle area are governed by the door's internal framework and vapor barrier placement.
- A 6.5 inch speaker occupies a mid-sized cone diameter that balances low-frequency extension with physical fitment constraints typical of rear door cavities in compact luxury sedans.
- In a rear door panel installation, the speaker fires laterally into the cabin, meaning sound travels across the rear seating area rather than projecting directly toward the front listening position.
- The 6.5 inch diameter in a rear door mount produces a cone surface area sufficient to move enough air for meaningful bass and midrange reproduction without requiring the structural reinforcement that larger drivers would demand from the door panel.
- Midbass drivers are acoustically specialized for the frequency range roughly between 80 Hz and 500 Hz, reinforcing the lower midrange and upper bass frequencies that contribute to body and warmth in music reproduction at the rear door position.
- Full-range drivers cover a broader frequency span, from low bass through upper treble, allowing a single driver at the Cadillac ATS rear door panel location to handle all audio frequencies without a dedicated companion tweeter at that position.
- The rear door panel of the Cadillac ATS accommodates either a midbass or full-range type in the 6.5 inch cutout, indicating the mounting ring diameter and depth clearance are consistent between both driver types at that size.
- Midbass drivers at the rear door location typically feature stiffer suspensions and heavier cone assemblies compared to full-range drivers, which affects excursion characteristics and the mechanical load placed on the door mounting surface.
- A full-range driver in the rear door panel of the Cadillac ATS + 2013-2016 model years must handle high-frequency content from a location that is physically distant and off-axis from front passengers, which influences the perceived treble dispersion in the cabin.
- The 6.5 inch cutout diameter at the rear door panel location determines the mounting hole size required in the door skin, and both compatible driver types share a specification set to that opening.
