Design and Build: The XS-690ES coaxial speakers by Sony are likely designed to fit into standard car speaker openings. They are built with automotive environments in mind, featuring materials and construction that can withstand temperature fluctuations, vibrations, and other challenges commonly encountered in vehicles.

Speaker Components: Coaxial speakers generally incorporate multiple speaker elements within a single unit. This could include a woofer, midrange driver, and a tweeter. The woofer handles the lower frequencies (bass and midrange), while the midrange driver and tweeter manage the midrange and high frequencies, respectively.

Sound Quality: Sony's XS-690ES coaxial speakers would likely aim to provide high-quality sound reproduction for an improved audio experience in your car. The combination of different speaker components helps to achieve a broader frequency range and more balanced sound compared to stock factory speakers.

Installation: Installation of coaxial speakers often involves replacing the existing factory-installed speakers. This might require some level of expertise, as it can involve removing interior panels to access the speaker locations. It's important to ensure compatibility with your vehicle's audio system and follow installation instructions provided by Sony.

Additional Features: Modern coaxial speakers may come with various additional features to enhance sound quality and usability. These could include features like advanced cone materials for improved sound dispersion, built-in crossovers for better frequency separation, and enhanced damping materials to reduce unwanted vibrations.
