Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-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 Hyundai Equus rear door panel accommodates a 3-way speaker configuration across all listed model years, with dedicated mounting positions for a 1 inch tweeter, a 2.5 inch midrange, and a 6.5 inch midbass/full-range driver within the same door panel.
- Door panel installations place speakers within an enclosed, irregular cavity formed by the door's inner skin, outer skin, and structural reinforcements, which affects acoustic loading and low-frequency reproduction compared to open-air or sealed enclosures.
- The rear door panel location positions speakers at roughly seat-level height for rear passengers, which influences the listening axis and proximity relative to occupants seated in the rear cabin.
- A 6.5 inch driver in a midbass or full-range role handles the lower portion of the audible spectrum, typically from around 60 Hz up through the midrange frequencies, and the door panel cavity serves as a passive acoustic chamber that interacts with the driver's rear wave, influencing bass response in the rear seating area.
- The 6.5 inch format is a widely used automotive driver diameter that fits within standard door cavities while maintaining sufficient cone area to move enough air for low-frequency output at typical listening volumes.
- A 2.5 inch midrange driver is designed to handle the vocal and instrumental presence range, generally from around 300 Hz to several kilohertz, where human speech intelligibility and instrument clarity are concentrated.
- At 2.5 inches, the cone area is small enough to allow controlled, directional high-midrange reproduction without the beaming artifacts associated with larger drivers attempting to reproduce the same frequencies.
- The Hyundai Equus rear door panel placement of the 2.5 inch midrange positions mid-frequency reproduction near the rear passenger's ear level within the door structure, rather than relying on front speakers to project midrange rearward.
- A 1 inch tweeter reproduces high frequencies, typically from around 2 kHz to 20 kHz, where wavelengths are short enough that even small driver diameters produce adequate sound pressure levels with relatively low moving mass.
- Tweeters are highly directional at the upper end of the audio spectrum, so the rear door panel mounting position of the 1 inch tweeter in the Hyundai Equus determines the high-frequency dispersion pattern experienced by rear-seat occupants.
- The combination of a dedicated tweeter, midrange, and midbass/full-range driver in a single door panel represents a multi-way system where crossover frequencies divide the audio signal so each driver operates within an acoustically appropriate range for its size and type.
- Door panel speaker cutouts are sized precisely to the specified driver diameter, meaning the 1 inch, 2.5 inch, and 6.5 inch dimensions correspond to the physical mounting apertures present in the rear door panel of the Equus across the listed model years.
