Product Overview
2-Way Coaxial Speakers 120 Watts 4-Ohm
The power, clarity, and range everyone who likes it LOUD loves about the GEN-X series returns in a speaker equipped with an extremely durable steel basket to outlast any vehicle it’s installed in. Making it the perfect choice for anyone looking for a long-lasting and reliable speaker. This is particularly important in the case of car audio systems, as the constant vibrations and movement of a car can cause damage to less robust speakers.
The G4Xi was made for amplifiers but can be used in factory settings with 4-ohm factory amplifiers in most cases for great sound and clarity over factory OEM speakers.
The G4Xi is notable for its 2-way design consisting of a woofer, and a tweeter. The different drivers are each responsible for reproducing sounds within a specific frequency range, allowing for a more accurate and full-sounding audio experience. The G4Xi’s 2-way design also ensures that the speaker does not require a large amount of power to operate, making it suitable for use with a variety of amplifiers.
The Mylar Balanced Dome Tweeters included in this coaxial help it achieve the highest range of frequencies possible, while the speaker itself reaches frequencies as low as 80Hz.
These speakers get loud extremely easily with a MAX Power Handling of 120W and RMS Power Handling of 40W.
Whether you’re turning up the volume or appreciating the nuances in your favorite tracks, the G4Xi will deliver. Order yours today and take the first step towards audio perfection on the road.
