Infinity Component Speakers INFSPKRF407FUS Editorial Review
The Infinity Reference 4" coaxial speakers have garnered positive feedback from customers who have upgraded their vehicles, particularly in the 2023 Bronco model. Users have noted a remarkable improvement in sound quality over the stock OEM speakers, which they characterized as subpar with a lack of bass and clarity. The Infinity speakers, known for their efficiency and sound reproduction, are praised for their ability to deliver better mids and lows, significantly enhancing the listening experience. One customer who replaced the front dash speakers reported that the upgrade made a "huge difference," and they were eager to proceed with installing them in the rear pods. The brightness of the sound, often due to reflection from the windshield, was a common observation, leading some users to adjust treble settings for a more balanced output. Importantly, the speakers are designed to handle the factory head unit's power without the need for an amplifier, making them an attractive option for those looking for easy improvements without extensive modifications. Installation is generally straightforward, especially with the use of adapter harnesses that allow for plug-and-play set-up, though some users did mention that minor trimming of the mounting tabs was required for a proper fit in the Bronco. However, potential buyers should note the limited versatility with specific vehicle models, as some reported compatibility issues when trying to install in different vehicles. In summary, the Infinity Reference 4" speakers appear to be a highly recommended upgrade for those looking to improve their audio experience in select vehicles like the Bronco, delivering great value through enhanced sound quality and ease of installation. **
