The Acura RLX dashboard accommodates a 3 inch speaker size across all listed model years. Full-range units are the compatible audio type for the system. These specifications cover the 2014 to 2017 model year 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 dashboard location in the Acura RLX accommodates a 3-inch speaker across the 2014, 2015, 2016, and 2017 model years.
A 3-inch speaker occupies a shallow, compact mounting footprint, which aligns with the constrained depth and surface area typically available within a dashboard enclosure.
Dashboard installations are positioned at the front of the cabin near the windshield, placing the speaker at a high horizontal plane relative to seated occupants, which affects the perceived directionality of sound toward the listener.
The small diameter of a 3-inch driver corresponds to a limited cone surface area, which is acoustically suited to reproducing upper-midrange and high-frequency content rather than extended low-frequency output.
Full-range is the sole compatible speaker type listed for the Acura RLX dashboard position, meaning a single driver in the location is intended to handle the entire audible frequency spectrum assigned to that mounting point.
A full-range driver in a dashboard position typically reinforces presence frequencies, approximately 2 kHz to 5 kHz, which contribute to vocal clarity and instrument definition as perceived from the front of the listening field.
The 3-inch form factor in a dashboard position limits excursion capability, meaning the driver's physical movement range restricts low-frequency extension and maximum sound pressure output at bass frequencies.
Dashboard-mounted full-range drivers in the 3-inch class are commonly crossed over or filtered within a multi-speaker system to operate within the frequency band where the small cone size performs most efficiently.
