Eagle Summit Dashboard Speaker Size
The Eagle Summit dashboard accommodates a 4 inch speaker size across all listed model years. Midrange units are the compatible speaker type for the dashboard location. These specifications cover a range from 1989 to 1995.
| Year | Type | Size (inch) |
|---|---|---|
| 1995 | Midrange | 4 |
| 1994 | Midrange | 4 |
| 1993 | Midrange | 4 |
| 1992 | Midrange | 4 |
| 1991 | Midrange | 4 |
| 1990 | Midrange | 4 |
| 1989 | Midrange | 4 |
Speaker Types
| Type | Description |
|---|---|
| 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 dashboard location in the Eagle Summit positions speakers at the front of the cabin, near the base of the windshield, placing sound sources at a forward-facing angle toward the listening area.
- Dashboard installations typically involve shallow mounting depth constraints, as the dashboard cavity must accommodate the instrument cluster, HVAC ducting, and structural components alongside speaker hardware.
- The 4-inch diameter specified for the Eagle Summit dashboard indicates a compact driver suited to the limited baffle space available in a dashboard mounting environment.
- A 4-inch driver produces sound within a frequency range that spans the upper bass through the lower treble, with the most controlled output occurring in the midrange band between approximately 300 Hz and 5 kHz.
- The smaller cone area of a 4-inch driver results in relatively limited low-frequency extension compared to larger drivers, which aligns with the acoustic limitations of a dashboard enclosure that lacks the air volume needed to support deep bass reproduction.
- Midrange speakers are designed to reproduce the central portion of the audible frequency spectrum, covering the frequencies most present in vocals, speech, and a wide range of acoustic instruments.
- Midrange drivers are typically built without the heavy excursion components found in woofers or the lightweight high-frequency diaphragms found in tweeters, concentrating their mechanical design on accurate reproduction within the mid-frequency band.
- A midrange speaker placed in the dashboard benefits acoustically from the forward-facing position, as the frequencies handled by a midrange driver are directional enough that placement relative to the listener influences perceived clarity and imaging.
- The combination of a 4-inch diameter and midrange type in the dashboard location reflects a consistent acoustic approach across all listed model years, with the dashboard serving a mid-frequency role in the front soundstage.
