Features
PEI Dome Tweeter: Each speaker has a PEI (Poly-Ether-Imide) dome tweeter. PEI is a polymer film that produces a wide soundstage to improve imaging.
Woofer: The woofer cones are made of water-repellent treated paper.
Size Classification Note: Some manufacturers, including Hertz, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size speaker as a 6-3/4". Please enter your vehicle information to confirm fit.

I just swapped these for the factory "B&O" speakers in my 2021 Bronco kick panels. Noticeable improvement in the depth of sound and enhanced midrange. Super happy so far.
