Dodge Colt Rear Door Panel Speaker Size
The Dodge Colt rear door panel accommodates a 4 inch speaker size. Midrange units are the compatible audio types for the system. These specifications cover the 1991 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 1991 | 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 rear door panel location in the 1991 Dodge Colt accommodates a 4-inch speaker cutout, which reflects a relatively compact mounting cavity within the door's interior trim panel.
- Door panel installations are typically surface-mounted or recessed into a molded cavity, with the speaker basket depth being a critical factor to avoid interference with the door's window regulator mechanism or inner metal skin.
- A 4-inch driver in a door panel position operates within a partially enclosed, irregular acoustic space, as the door cavity behind the cone acts as an unintentional enclosure that can influence low-frequency response.
- The 4-inch diameter limits the effective radiating cone area, which concentrates the driver's output in the upper-mid frequency bands rather than the lower bass registers.
- Midrange drivers are specifically designed to reproduce the frequency band roughly between 500 Hz and 5,000 Hz, covering the range most associated with vocal clarity and instrument presence.
- In a rear door panel position, a midrange driver's directional output is aimed laterally into the cabin, angling toward the passenger seating area rather than projecting forward or rearward.
- The Dodge Colt rear door panel's 4-inch midrange specification indicates the mounting location is dimensionally constrained, as larger woofer or coaxial configurations are not listed as compatible for the 1991 model year in this position.
- Midrange drivers typically use a relatively shallow basket profile compared to woofers, which is relevant for door panel installations where clearance between the speaker and the door's inner metalwork is limited.
- Because midrange drivers do not require a large enclosure volume to perform within their intended frequency range, the irregular door cavity volume has less acoustic impact on midrange output than it would on a woofer.
