Infinity REF507CF Reference Series 5.25" Component Speakers — Extreme-Performance

Designed for high-output, detailed playback, the Infinity REF507CF Reference Series component speakers use audiophile-grade tweeters that stay smooth and non-fatiguing even at elevated volume. On larger Reference multielement and component systems, a tweeter output level control is provided to help match system balance to installation position or listener taste. These speakers incorporate Harman’s patented Plus One™ cones (US patent #7,548,631) that deliver more cone surface area than competing cones in their class — yielding greater sensitivity, stronger low-frequency output and faithful music reproduction. Reference models come in a variety of standard sizes and feature a compact footprint so they can be installed in nearly any vehicle on the road today.
