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.
