T1650-S Euro Fit

The Rockford Fosgate T1650-S Euro Fit from the high-end Power T1 series is a powerful 16.5 cm (6.5-inch) 2-way component speaker system designed for demanding car audio applications. With an 80-watt RMS power handling capacity, separate 25-mm fabric-dome tweeters, and meticulously tuned crossovers, the system delivers dynamic, detailed, and precise music reproduction.

The carbon-fiber-reinforced polypropylene cone, combined with VAST technology, provides an increased effective cone area and powerful bass reproduction. The sturdy aluminum baskets with the FlexFit 2 mounting system make installation easy in a wide range of vehicle models. The external crossovers allow you to individually adjust the treble level, tweeter alignment, and bi-amping operation.
