New Reference speakers are designed to deliver Infinity’s signature sound in more vehicles. They feature edge-driven textile tweeters for smooth, clear highs and the larger models offer an adjustable tweeter output level control for high-frequency optimization based on installation location or the listener’s preference. Oversized Plus One™ woofers offer more surface area for higher bass output and enhanced midrange performance. Plus our newly engineered baskets are optimized to fit most factory speaker locations. Available in a range of standard sizes—3″, 4″, 5-1/4″, 6-1/2″, 6″ x 8″ and 4″ x 6″ coaxial, 6″ x 9″ 3-way, and 5-1/4″, 6-1/2″, and 6″ x 9″ component—they’re the perfect upgrade from factory speakers.
