Acura ILX Rear Deck Lid Speaker Size
The Acura ILX rear deck lid accommodates an 8 inch speaker size and 3 inch speakers across all listed model years. Compatible speaker types for these locations include woofer and full-range units. The specifications cover a range of years from 2013 to 2017.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Woofer | 8 |
| 2017 | Full-Range | 3 |
| 2016 | Woofer | 8 |
| 2016 | Full-Range | 3 |
| 2015 | Woofer | 8 |
| 2015 | Full-Range | 3 |
| 2014 | Woofer | 8 |
| 2014 | Full-Range | 3 |
| 2013 | Woofer | 8 |
| 2013 | Full-Range | 3 |
Speaker Types
| Type | Description |
|---|---|
| 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 ILX rear deck lid accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver configuration within a single installation zone.
- The rear deck lid is a horizontal surface positioned at the rear of the passenger cabin, between the back seats and the trunk, placing speakers in a rearward-facing or upward-facing orientation relative to the listening area.
- An 8-inch woofer in the Acura ILX rear deck lid operates within the low-frequency range, typically handling bass and upper-bass reproduction, where larger cone surface area moves greater air volume to produce deeper, more powerful low-end output.
- The rear deck lid location places the 8-inch woofer at a distance from the front listening position, a placement that takes advantage of low-frequency omnidirectionality, as bass frequencies below roughly 200 Hz are less sensitive to positional localization.
- A woofer is a dedicated low-frequency transducer, meaning the 8-inch driver in the ILX rear deck is not intended to reproduce midrange or high-frequency content independently and typically requires crossover filtering to operate within its designed frequency band.
- The 3-inch driver designated for the same rear deck lid location is classified as full-range, meaning a single cone handles the full audible spectrum from low to high frequencies, though the small diameter limits its low-frequency extension and output compared to larger drivers.
- A 3-inch full-range driver in a rear deck position contributes upper midrange and treble content to the rear soundstage, with the small cone mass enabling relatively quick transient response at higher frequencies.
- The physical proximity of the 3-inch full-range and 8-inch woofer within the same rear deck lid zone means both drivers share the same general radiation point, allowing their frequency output to integrate within the rear cabin space.
- The rear deck lid surface in a compact sedan like the ILX is subject to structural resonance, and the mass of an 8-inch woofer mounted there may require adequate bracing or baffling to prevent panel vibration from coloring the acoustic output.
- The 3-inch diameter constrains cone area to approximately 7 square inches of radiating surface, limiting the amount of air displacement available for low-frequency reproduction and reinforcing the frequency division of labor between the 2 drivers in the rear deck lid.
