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 - 3-1/2", 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.

Harman’s patented (US patent #7,548,631) Plus One™ cones provide more overall speaker-cone area than other cones in its class - the result is higher sensitivity, increased low-frequency output and accurate music reproduction.
Reference speakers are available in a range of standard sizes, and feature a compact design that allows them to fit just about any vehicle on the road today.
