Acura RSX Dashboard Speaker Size
The Acura RSX dashboard accommodates a 1.5 inch speaker size across all applicable model years. Tweeter units are the compatible speaker type for the dashboard location. The specifications cover the 2002 to 2006 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2006 | Tweeter | 1.5 |
| 2005 | Tweeter | 1.5 |
| 2004 | Tweeter | 1.5 |
| 2003 | Tweeter | 1.5 |
| 2002 | Tweeter | 1.5 |
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. |
Additional Notes
- The dashboard location in the Acura RSX accepts a 1.5 inch speaker across all listed model years.
- Dashboard placement positions a speaker at the forward-most point of the cabin, near the base of the windshield, which places the sound source at ear level and toward the front of the listening field.
- The shallow depth and limited cavity space typical of a dashboard installation constrains the physical size of any speaker that can be mounted there, making compact drivers a functional necessity rather than an aesthetic choice.
- A 1.5 inch driver diameter falls within the range commonly associated with high-frequency reproduction, as smaller cone surface areas move less air but respond faster to rapid signal changes, which is appropriate for treble content.
- The Acura RSX dashboard is specified exclusively for tweeter-type speakers, meaning the location is not intended to handle mid-range or bass frequencies.
- Tweeters operate in the upper portion of the audible frequency spectrum, generally handling frequencies above approximately 2,000 Hz, and the dashboard position directs high-frequency energy toward the listener's ear plane rather than downward from door panels.
- High-frequency sound waves are highly directional, and a forward dashboard mounting position in the Acura RSX places the tweeter on an axis more closely aligned with the listener than a door or kick panel location would allow.
- The 1.5 inch form factor in the Acura RSX dashboard is consistent with a tweeter's mechanical requirements, as tweeters use lightweight dome or cone diaphragms that do not require the larger excursion or basket depth associated with woofers or full-range drivers.
