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 deck lid of the Toyota Tercel is a horizontal surface positioned at the base of the rear window, above the trunk cavity, placing speakers in a location that projects sound upward and forward into the cabin.
- Mounting on a rear deck lid typically involves a flat or slightly contoured panel, which requires speakers with standard depth clearance to avoid contact with the trunk structure beneath.
- The 6.5 inch driver size fits the rear deck lid opening on the Toyota Tercel for model years 1991 through 1998, as well as one configuration of the 1990 model year.
- A 6.5 inch cone area produces meaningful cone surface relative to smaller sizes, which supports stronger low-midrange output and greater air displacement from a rear deck position.
- The 5.25 inch driver size is the specified fitment for the Toyota Tercel rear deck lid across model years 1987 through 1989, and one configuration of 1990.
- A 5.25 inch speaker has a smaller cone area than a 6.5 inch unit, which generally results in a higher low-frequency rolloff point and a slightly tighter dispersion pattern from the same rear deck location.
- Both speaker sizes in the specifications are limited to midbass and full-range types, excluding dedicated tweeters or subwoofers from this mounting location.
- A midbass driver is optimized for frequencies roughly between 80 Hz and 500 Hz, covering the lower midrange and upper bass registers that contribute to vocal body and instrumental warmth when positioned at the rear deck.
- A full-range driver is designed to reproduce a broad frequency band, typically from around 60 Hz to 20 kHz, allowing a single driver at the rear deck lid to handle the entire audible spectrum without a crossover.
- The rear deck lid position places the speakers behind the primary listening area, meaning sound from the rear deck travels over the rear seat and reflects off the rear glass before reaching front occupants.
- The 1990 model year is the only year in the specifications associated with both a 6.5 inch and a 5.25 inch fitment, indicating 2 distinct rear deck configurations existed within that production year.
