All About
Infinity Car Speakers
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.
We love people and we're ready to help you! See what separates us from our competition.
