The Ford Edge center dash location accommodates a 3.5 inch speaker size. Full-range units represent the compatible audio type for the center dash. These specifications apply to the 2018 system year.
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 center dash location in the Ford Edge positions a speaker at the upper central point of the instrument panel, a placement that prioritizes forward-facing sound projection toward the cabin's listening area.
A 3.5 inch speaker in a center dash position occupies a shallow, space-restricted cavity typical of instrument panel construction, where depth clearance is limited by the underlying dash structure and HVAC components.
The small diameter of a 3.5 inch driver means the cone surface area is modest, which suits the tight physical envelope of a center dash mounting location where larger frames would not fit within the panel's housing.
A 3.5 inch speaker reproduces upper-midrange and high-midrange frequencies effectively, generally covering approximately 200 Hz to 5 kHz, which in a center dash position aligns with the spatial origin of vocals and dialogue in an audio mix.
The center dash placement creates a centralized stereo image anchor point, and the frequency range a 3.5 inch driver handles is well suited to reinforcing that phantom center stage effect between left and right channels.
A full-range speaker type is designed to handle the entire audible spectrum from a single driver, without relying on external crossovers to divide the signal into separate frequency bands.
In a center dash location, a full-range driver operating without a passive crossover network allows direct signal input, which is consistent with factory head unit configurations that send a full-bandwidth signal to each speaker channel.
The Ford Edge center dash full-range speaker for the 2018 model year accepts a signal covering lows through highs from a single voice coil and cone assembly, making the driver responsible for both lower midrange body and upper midrange clarity from one location.
Because a 3.5 inch full-range driver has a relatively small excursion range, bass extension below approximately 150 to 200 Hz is limited, meaning the center dash position in the 2018 Ford Edge does not serve as a low-frequency source in the vehicle's audio system.
