Saturn LW2 Rear Door Panel Speaker Size
The Saturn LW2 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio system units. These specifications cover the year 2000.
| Year | Type | Size (inch) |
|---|---|---|
| 2000 | 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 places speakers within the lower portion of the door cavity, where the mounting surface is typically oriented to project sound upward and inward toward the cabin floor and seating area.
- Door panel installations at the rear position are subject to spatial constraints from door card thickness, window regulator mechanisms, and inner door skin depth, all of which affect the maximum basket depth a speaker can occupy.
- A 6.5-inch driver occupies a cone area suited to reproducing frequencies roughly between 60 Hz and 5 kHz, making the rear door panel a productive location for mid-to-low frequency reinforcement within the Saturn LW2 cabin.
- The physical diameter of a 6.5-inch speaker requires a mounting cutout and baffle area that must clear the inner door panel structure, a factor specific to the LW2 rear door geometry for the 2000 model year.
- Midbass drivers are designed to focus on the lower-middle portion of the audible spectrum, approximately 80 Hz to 500 Hz, and in a rear door location, a midbass unit contributes lower-frequency body and warmth to the overall cabin sound field.
- Full-range drivers are engineered to reproduce a wide span of frequencies from bass through treble within a single cone and, when installed in the Saturn LW2 rear door panel, handle the entire audible range from a single mounting point without requiring additional high-frequency support at that position.
- Rear door speaker locations generally exhibit a longer path length to front-seat listeners compared to front door or dash positions, which affects the time-arrival characteristics of frequencies reproduced by drivers mounted there.
- The 6.5-inch format, when loaded into a door panel cavity, uses the internal door volume as an acoustic space behind the cone, and the size of that air volume influences low-frequency extension and bass output of whichever compatible driver type is installed.
