    All About

    Infinity Car Speakers
    Infinity car speakers are engineered from the ground up to deliver rich, full sound in the challenging environment of a car. Infinity has a high quality option in a wide variety of sizes, making it easy to find Infinity car speakers that fit your car. Infinity speakers, like the Kappa and Reference series, are available in component systems as well as coaxial speakers, enabling them to work well in virtually any environment.

    The Infinity Kappa series are a sure bet to impress even the most discerning audiophiles with crisply defined treble and bold, powerful sound. The Kappa speakers deliver fantastic sound quality and beautiful highs thanks to their high quality materials and construction, over sized cones and edge driven dome tweeters.

    Other options available from Infinity include the Reference and Reference X series speakers. The Reference speakers are a mix of classic coaxial speakers and component systems with multiple mounting options for your convenience. The Plus One cone design provides incredibly smooth mid-range sounds for each speaker while the edge driven textile dome tweeters produce crystal clear highs. The Reference X speakers were designed with a vented motor assembly to reduce heat buildup to allow the speakers to maintain a higher output level for a longer period of time.

    Infinity car speakers take advantage of the tremendous Infinity engineering for outstanding power handling, sound quality and speaker life. From 5" x 7" and 6" x 9" to 5.25" to 6.5" speaker configurations, we have every Infinity speaker to help you create the best sound system around at Sonic Electronix.
