2x Infinity REF687F 6x8" Extreme-performance automotive coaxial speakers - (REF687F)
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, they’re the perfect upgrade from factory speakers.
Features and Benefits
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.
