About: Infinity Reference REF-4032cfx 4" 35W RMS 2-Way Coaxial Speakers 

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.

Edge-driven, textile tweeters

The audiophile-grade tweeters used in Infinity's new Reference speakers deliver smooth, non-fatiguing sound even at high output levels.

Adjustable tweeter output level

The larger Reference multielement and component systems offer a tweeter output level control to optimize system linearity to suit installation location or the listener's preference. 

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 accurate music reproduction.

Optimized Frame Size 

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.
