Acura TSX Dashboard Speaker Size
The Acura TSX dashboard accommodates a 3 inch speaker size and 1 inch speakers, reflecting the 2 unique sizes found across the model's production span. Compatible audio system types for the dashboard position include full-range units and tweeters. These specifications cover the 2004 to 2014 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2014 | Full-Range | 3 |
| 2013 | Full-Range | 3 |
| 2012 | Full-Range | 3 |
| 2011 | Full-Range | 3 |
| 2010 | Full-Range | 3 |
| 2009 | Full-Range | 3 |
| 2008 | Tweeter | 1 |
| 2007 | Tweeter | 1 |
| 2006 | Tweeter | 1 |
| 2005 | Tweeter | 1 |
| 2004 | Tweeter | 1 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| 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 TSX dashboard speaker location accommodates 2 distinct speaker configurations across the model range: a 3-inch full-range unit and a 1-inch tweeter.
- Dashboard placement positions speakers at the forward edge of the listening environment, near the base of the windshield, which places the drivers close to ear level and at the front of the soundstage.
- The shallow depth and limited enclosure volume typical of dashboard cavities impose physical constraints on cone excursion and low-frequency reproduction, favoring smaller drivers with modest displacement requirements.
- A 3-inch full-range driver covers a broad frequency span within a single cone and voice coil assembly, typically handling midrange and upper-bass frequencies while also extending into high-frequency reproduction without a crossover network.
- In a dashboard position, the 3-inch full-range driver's ability to reproduce midrange frequencies directly supports vocal clarity and instrument presence, as the forward placement reinforces the front soundstage for occupants.
- A 1-inch tweeter is a high-frequency driver, generally responsible for reproducing frequencies above approximately 2,000 to 3,500 Hz, where treble detail, shimmer, and upper harmonic content reside.
- The 1-inch diameter of the tweeter reflects the small diaphragm size needed for accurate high-frequency dispersion; smaller diaphragms move faster and maintain pistonic motion at elevated frequencies more effectively than larger cones.
- Dashboard placement of a 1-inch tweeter takes advantage of the location's proximity to the listener, as high-frequency sound is highly directional and benefits from a position aimed toward the occupant's ear level.
- A tweeter installed in the dashboard requires a high-pass crossover, either passive or active, to block low and midrange frequencies that would otherwise exceed the driver's mechanical limits and cause distortion or damage.
- The 2009 through 2014 model years share the 3-inch full-range specification, while the 2004 through 2008 model years share the 1-inch tweeter specification, indicating a change in dashboard speaker configuration between the two generational groups.
