T3652-S

The Rockford Fosgate T3652-S from the high-end Power T3 series is an audiophile 2-way component system designed specifically for exceptional sound quality and precise music reproduction. With a 125-watt RMS power handling capacity, high-quality materials, and a sophisticated crossover, the speaker system delivers detailed sound reproduction with dynamic bass, natural mids, and clear highs.

The 16.5 cm mid-bass drivers feature exceptionally lightweight and rigid LCP (Liquid Crystal Polymer) cones, which deliver high fidelity with low distortion. VAST technology increases the effective radiating area of the cone, while the sturdy die-cast aluminum basket, the powerful neodymium driver, and the durable Nomex suspension ensure precise cone movement.

The 25 mm LCP dome tweeters with aluminum phase plugs deliver highly detailed high-frequency reproduction. Thanks to the DDC mounting system, the tweeters can be flexibly mounted either flush or at an angle.

The included external crossovers offer three-step treble level adjustment, switchable on-axis/off-axis tuning, and a bi-amping function for separate amplification of the tweeters and mid-woofers.
