Ford Fusion Front Door Panel Speaker Size

Additional Notes

• The Ford Fusion front door panel accommodates a 2-speaker configuration per door, combining a small-diameter tweeter mounted in the upper panel area with a larger woofer or full-range driver mounted lower in the door cavity.
• Door panel locations position speakers within an enclosed air cavity formed by the door's inner and outer skins, which affects the low-frequency loading of the larger driver and the acoustic reflection behavior of the tweeter.
• The 6.5 inch driver size, present in model years 2013 through 2020, fits within a circular cutout and mounting ring standard to mid-size automotive door panels, where the door cavity volume supports the cone excursion needed for bass and lower midrange reproduction.
• A 6.5 inch midbass or full-range driver in the front door of the Ford Fusion handles frequencies typically from the low bass region up through the midrange, approximately 50 Hz to 5,000 Hz, depending on crossover configuration and cone material.
• The 6x8 inch oval format used in model years 2010 through 2012 occupies a larger footprint than a 6.5 inch round driver, requiring an oval cutout in the door panel, while producing a comparable effective radiating area for low-to-mid frequency reproduction.
• The 5x7 inch oval driver format used in model years 2006 through 2009 is a smaller oval than the 6x8 inch format and corresponds to a distinct mounting template with a shorter major axis, affecting both the door panel cutout geometry and the driver's low-frequency extension capability.
• Full-range designation on the oval drivers in model years 2006 through 2012 indicates a single driver intended to reproduce the entire audible spectrum without a dedicated crossover, though the door panel's physical position limits high-frequency dispersion due to the driver's size and directional beaming at higher frequencies.
• Midbass designation, listed for 6.5 inch drivers in model years 2013 through 2020, describes a driver optimized for bass and lower midrange frequencies and is typically used in a component system where a crossover routes high frequencies to a separate tweeter.
• The 1 inch tweeter size, specified for model years 2010 through 2020, is a small dome or cone driver mounted in the upper section of the front door panel, positioned to improve high-frequency dispersion toward the listening area at ear level.
• A 1 inch tweeter handles high-frequency content generally above 2,000 Hz to 3,500 Hz depending on crossover slope, and at the Ford Fusion front door panel location, the upper mounting position reduces path length differences between the tweeter and the listener compared to a floor-mounted alternative.
• The 1.5 inch tweeter size found in model years 2006 through 2009 has a larger radiating surface than the 1 inch format, which can extend its usable frequency range slightly lower and affect the crossover point at which it transitions from the full-range driver below it.
• The front door panel location places both drivers on a vertical surface angled toward the vehicle's interior, a geometry that influences the horizontal dispersion pattern of the tweeter and the off-axis frequency response of the larger driver at mid and upper frequencies.
