The Audi A3 center dash location accommodates a 3.5 inch speaker size. Full-range units are the compatible audio system types for the center dash. These specifications cover the 2015 to 2018 model years.
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 Audi A3 sits at the top of the instrument panel, positioned along the vehicle's central axis between the driver and front passenger.
A center dash mounting position places the speaker at or near ear level for front occupants, orienting sound output upward and rearward toward the cabin.
The 3.5-inch diameter specified for the Audi A3 center dash reflects a compact mounting cavity, consistent with the shallow depth and limited surface area typical of instrument panel speaker cutouts.
At 3.5 inches, the cone surface area is relatively small, which limits low-frequency displacement but suits the spatially constrained center dash enclosure where larger drivers would not physically fit.
The 3.5-inch size in a center dash position is acoustically suited to upper-midrange and high-midrange reproduction, roughly covering frequencies from approximately 200 Hz to 5 kHz with meaningful output.
Full-range drivers are designed to reproduce the audible frequency spectrum from a single cone, without the signal filtering or crossover networks required by component speaker systems.
In a center dash application, a full-range driver handles vocals and dialogue frequencies without relying on an external crossover, which aligns with the single-unit mounting format of the location.
The center dash position in the Audi A3 is a dedicated single-speaker location, meaning the cutout accommodates 1 driver rather than a multi-speaker array.
Full-range compatibility at the center dash position indicates the speaker receives a full, unfiltered signal, requiring the driver cone to manage both lower midrange body and upper midrange clarity simultaneously.
