Saturn L300-2 Rear Door Panel Speaker Size
The Saturn L300-2 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. These specifications apply to the 2004 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2004 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| 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 rear door panel location positions speakers within the lower portion of the door cavity, where the speaker fires inward toward the cabin occupants at seat level.
- Door panel mounting typically involves a basket-to-panel interface secured by screws or bolts, with the speaker cone facing the interior through a grille or cutout in the door trim.
- A 6.5-inch driver in a rear door panel occupies a mid-sized mounting footprint, balancing cone surface area against the spatial constraints of a door cavity that must also accommodate window mechanisms and wiring.
- The 6.5-inch cone diameter produces sufficient radiating surface to move air efficiently in the lower midrange and upper bass frequencies, which are acoustically relevant in a rear door environment where low-frequency reinforcement supports the front soundstage.
- The Saturn L300-2 rear door panel accepts a 6.5-inch speaker, a dimension that determines the outer diameter, mounting hole diameter, and depth clearance required for a compatible driver.
- A midbass driver in a rear door is suited to reproducing frequencies roughly between 80 Hz and 500 Hz, covering the lower vocal range and upper bass fundamentals without extending into high-frequency reproduction.
- A full-range driver spans a broader frequency band than a dedicated midbass unit, typically covering bass through lower treble, and in the rear door location handles audio reproduction without requiring a separate tweeter in that zone.
- The rear door panel location places the speaker behind and below seated passengers, meaning the driver's output travels a short distance before interacting with seat materials and the rear cabin volume.
- Door cavities in sealed or semi-sealed configurations can influence the rear acoustic loading on a cone, affecting the bass response characteristics of whichever driver type is installed.
