Infinity REF697F 6x9 Coaxial Car Speakers — Extreme-Performance

The Infinity REF697F 6x9 coaxial speakers feature audiophile-grade tweeters designed to remain smooth and non-fatiguing even at high output. On larger Reference multielement and component systems, a tweeter output level control is provided so you can optimize system linearity for the installation location or personal listening preference. These speakers use Harman’s patented (US patent #7,548,631) Plus One cones, which deliver more overall speaker-cone area than others in their class — producing higher sensitivity, enhanced low-frequency output and accurate music reproduction. Reference models are offered in a range of standard sizes and their compact design allows installation in virtually any vehicle on the road today.
