The Acura TLX center dash location accommodates a 3.5 inch speaker size. Full-range units represent the compatible speaker types for the center dash. These specifications cover the 2018 model 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 Acura TLX places a speaker near the top of the instrument panel, positioning the driver for a centrally focused soundstage across the cabin.
A 3.5-inch driver in a center dash position occupies a shallow, space-constrained mounting cavity, which is typical of instrument panel installations where depth is limited by the underlying dashboard structure.
The 2018 Acura TLX center dash speaker uses a 3.5-inch full-range driver, a critical compatibility fact given the specific dimensional and type constraints of the factory mounting location.
A 3.5-inch speaker produces a relatively compact cone area, which at the center dash position contributes to upper-midrange and high-frequency projection rather than low-frequency reproduction.
Full-range drivers are designed to reproduce the entire audible frequency spectrum within a single unit, handling lows, mids, and highs without requiring a crossover network.
In a center dash location, a full-range driver is typically responsible for anchoring center-channel audio content, such as vocal and dialogue frequencies, which generally fall between 300 Hz and 3,000 Hz.
The center dash position places the speaker at or near ear level for front passengers, which allows a 3.5-inch full-range driver to deliver directional sound without significant angular dispersion loss.
Mounting a full-range driver in the center dash means the enclosure volume is determined entirely by the cavity formed within the dashboard structure, rather than a dedicated speaker enclosure.
