Ford Explorer Sport Trac Behind Rear Seat Speaker Size
The Ford Explorer Sport Trac behind rear seat location accommodates an 8 inch speaker size across all listed model years. Compatible types for the position include subwoofer replacement units suited for audio system upgrades. The specifications chart covers the 2007 to 2010 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2010 | Subwoofer | 8 |
| 2009 | Subwoofer | 8 |
| 2008 | Subwoofer | 8 |
| 2007 | Subwoofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The behind rear seat location in the Ford Explorer Sport Trac is a dedicated enclosure positioned at the rear of the cabin, behind the passenger seating area, which places the speaker in a low, rearward-facing orientation relative to the main listening space.
- An 8-inch driver occupies a mid-range point in subwoofer sizing, large enough to displace sufficient air for meaningful bass reproduction while fitting within the spatial constraints of a behind-seat cavity.
- The behind rear seat position typically provides a semi-enclosed or enclosed chamber formed by the seat structure and cargo area walls, which functions acoustically as a partial enclosure and influences bass loading on the driver.
- Subwoofers are dedicated low-frequency transducers, operating generally in the 20 Hz to 200 Hz range, and are designed exclusively to reproduce bass and sub-bass frequencies rather than midrange or high-frequency content.
- At 8 inches, the cone surface area is sufficient to move the air volume needed for low-frequency reproduction in a confined rear-cabin space without requiring the larger enclosure depth that a 10-inch or 12-inch driver would demand.
- The Ford Explorer Sport Trac behind rear seat location, carrying an 8-inch subwoofer specification across the 2007 through 2010 model years, reflects a consistent factory spatial allocation that constrains replacement driver diameter to 8 inches for physical fitment.
- Low-frequency sound waves have long wavelengths, making bass largely non-directional to listeners, which means the behind-the-seat placement does not significantly compromise perceived stereo imaging for the subwoofer's operating frequency range.
- The mounting depth available in a behind-seat location is a critical dimension for subwoofer installation, as subwoofers typically require greater depth than full-range speakers due to longer voice coil travel and larger magnet assemblies.
- Because subwoofers handle only the lowest frequencies, the 8-inch driver in the behind rear seat position functions as a dedicated bass channel supplementing separate mid-range and high-frequency speakers located elsewhere in the vehicle.
