T1T-S

The Rockford Fosgate T1T-S tweeter set from the high-end Power Series was designed for precise, detailed, and dynamic high-frequency reproduction. The two 25 mm (1") tweeters deliver brilliant highs and clear reproduction of the finest musical details. Thanks to their high-quality fabric domes, they deliver a balanced sound with high power handling.

The included external crossovers allow for optimal integration of the tweeters into the existing speaker system. With a crossover frequency of 3,000 Hz and a slope of 18 dB/octave, unwanted low frequencies are reliably filtered out. The adjustable high-frequency roll-off allows for individual tuning to the acoustic conditions inside the vehicle.

Thanks to the various mounting options, the tweeters can be flexibly installed in a wide range of vehicles. The special DDC mounting system facilitates flush mounting, while the angled surface-mount enclosures allow for precise alignment with the listening position.
