Mitsubishi Eclipse Dashboard Speaker Size
The Mitsubishi Eclipse dashboard accommodates a 1 inch speaker size and 4 inch speakers. Compatible audio types for the location include tweeters and midrange units. The specifications cover a system ranging from 1990 to 2012.

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. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The Mitsubishi Eclipse dashboard accommodates speakers in 2 distinct size formats across the listed model years: 1 inch and 4 inch.
- The dashboard location positions speakers in the forward-most section of the cabin, near the base of the windshield, which places them at ear level and in front of the listening position.
- A 1-inch driver in a dashboard position is physically constrained by shallow mounting depth and limited enclosure volume, which aligns with the acoustic demands of a tweeter, as tweeters require minimal air space behind the diaphragm to function correctly.
- Tweeters handle the upper portion of the audible frequency range, typically from around 2,000 Hz upward, and the forward dashboard placement in the Mitsubishi Eclipse positions high-frequency dispersion directly toward occupants.
- The 1-inch tweeter's small diaphragm area produces a relatively narrow dispersion pattern at the highest frequencies, making the dashboard a functionally appropriate location because the driver faces rearward toward seated occupants rather than being mounted in a side panel.
- A 4-inch midrange driver reproduces the middle band of the frequency spectrum, generally spanning from approximately 300 Hz to 5,000 Hz, which includes the fundamental frequencies of vocals and many instruments.
- The Mitsubishi Eclipse dashboard's 4-inch midrange specification indicates a mounting cavity with sufficient diameter and depth to seat a driver of that cone area, as 4-inch drivers require a meaningfully larger cutout and baffle surface than 1-inch tweeters.
- Midrange drivers in a dashboard location benefit acoustically from the reflective surface of the windshield, which can redirect sound energy back into the cabin and reinforce the perceived front soundstage.
- The 4-inch midrange driver's cone size produces greater sensitivity in the mid frequencies relative to a 1-inch tweeter, while still remaining compact enough to fit within the spatial constraints typical of a dashboard panel.
- In the 1990 through 1994 and 1993 model year entries, only the 4-inch midrange is listed for the dashboard, indicating those positions do not include a dedicated 1-inch tweeter opening within the dashboard location.
- For model years 1995 through 1999, the Mitsubishi Eclipse dashboard specifications list both a 4-inch midrange and a 1-inch tweeter, indicating the dashboard panel contains 2 separate mounting positions of different diameters within the same location zone.
- From 2006 through 2012, the dashboard specifications list only the 1-inch tweeter, indicating the dashboard mounting configuration for those years is sized exclusively for a small, high-frequency driver.
