T4652-S

The Rockford Fosgate T4652-S from the Power T4 series is a high-quality 16.5 cm (6.5") 2-way component system designed for demanding car audio applications and exceptionally precise sound reproduction. With a power handling capacity of 150 watts RMS per side, meticulously engineered speaker drivers, and a customizable crossover, the system offers an outstanding combination of dynamics, detail, and sound quality.

The low-midrange drivers feature exceptionally lightweight and torsionally rigid LCP (Liquid Crystal Polymer) fiber sandwich cones, which enable controlled, low-distortion sound reproduction. The special VAST technology (Vertical Attach Surround Technique) increases the effective usable cone area and supports powerful bass reproduction. A sturdy die-cast aluminum basket, a durable Nomex suspension, and a high-performance multi-pole neodymium magnet system round out the high-quality design.

For high-frequency reproduction, 25-mm LCP ring radiator tweeters with aluminum phase plugs are used. These enable exceptionally detailed and wide-ranging high-frequency reproduction up to 30,000 Hz. The included passive 2-way crossovers offer various adjustment options for optimal adaptation to the vehicle’s acoustics, including a three-step treble level adjustment, an on/off-axis switch, and the option for bi-amping.
