Acura TLX Rear Deck Lid Speaker Size
The Acura TLX rear deck lid accommodates a 6.5 inch speaker size and supports 8 inch speakers across the model's production span. Compatible audio types for these locations include woofer and midbass or full-range system units. These specifications cover the 2015 to 2018 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Woofer | 8 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Woofer | 8 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Woofer | 8 |
| 2015 | 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. |
| Woofer | A larger driver for low frequencies, typically from about 40 Hz up to 1,000 Hz. It delivers most of the bass and lower midrange in a door or panel speaker system. |
| 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 Acura TLX rear deck lid is a horizontal surface located at the base of the rear windshield, positioned above the trunk cavity and behind the rear passenger seating.
- Speakers mounted in the rear deck lid radiate sound upward toward the cabin, using the rear windshield glass as a reflective surface to disperse audio energy toward the front of the passenger compartment.
- The 6.5 inch speaker size appears across all model years listed in the specifications, making the mounting cutout associated with the 6.5 inch diameter a consistent dimensional characteristic of the Acura TLX rear deck lid.
- The 8 inch speaker size appears in the 2015, 2016, and 2017 model year specifications, indicating that the rear deck lid in those years accommodates a larger mounting cutout than the 6.5 inch position.
- A 6.5 inch driver in the midbass or full-range role at the rear deck lid location handles frequencies roughly between 80 Hz and 5 kHz, with full-range variants extending further into the upper midrange to cover vocals and instrumentation without a dedicated tweeter.
- The midbass type in the 6.5 inch size focuses on the lower-midrange and upper-bass frequencies, typically between 80 Hz and 500 Hz, reinforcing punch and body in musical material as heard from the rear of the cabin.
- An 8 inch woofer in the rear deck lid location operates most effectively in the bass and lower-midrange region, roughly from 40 Hz to 500 Hz, taking advantage of the deck lid's proximity to the trunk air volume, which can act as a passive acoustic chamber.
- The woofer type is designed for directional low-frequency output, and placement on the rear deck lid allows low-frequency waves to propagate along the length of the cabin, reaching front passengers with reduced cancellation compared to door-mounted positions.
- The presence of both an 8 inch woofer and a 6.5 inch midbass or full-range in the same model year specifications for 2015, 2016, and 2017 indicates the rear deck lid contains at least 2 distinct speaker mounting locations with different diameters in those years.
- In the 2018 model year specifications, only the 6.5 inch size is listed, indicating the rear deck lid mounting configuration for that year does not include the 8 inch woofer position present in prior years.
