Product Information

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 optimization based on installation location. Oversized Plus One™ woofers offer more surface area for higher bass output and enhanced midrange performance. Plus, their newly engineered basket is optimized to fit most factory openings. 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.

REF-6520CX Features:

Edge-driven, textile tweeters

The tweeters in Infinity Reference speakers play smooth, never-harsh regardless of output level.

Adjustable tweeter output level

The larger Reference coaxial models and the component systems offer a tweeter output level control of 0dB or +3dB to optimize system linearity based on installation location.

Plus One™ woofer cone architecture

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 greater musical character.

Optimized Frame Size

Reference speakers are available in a range of standard sizes, and feature a compact design that allows them to fit in just about any vehicle on the road today. That means signature Infinity sound in more vehicles.

Competitive pricing

Reference speakers provide signature Infinity sound at affordable prices.
