Know before you buy
Unlike traditional dome tweeters that push air, the Folded Motion tweeter uses a pleated diaphragm that squeezes air. This design provides significantly faster transient response and lower distortion, resulting in much higher clarity and detail in high-frequency sounds.
Yes, the F1 is specifically designed for smaller footprints. Its controlled dispersion technology helps minimize unwanted reflections off your walls and floors, making it easier to achieve high-quality sound in rooms where space is limited.
The F1 is quite efficient with a sensitivity of 92dB, meaning it doesn't require massive power to reach satisfying volumes. While it can handle up to 200 watts, it will perform well with most standard integrated amplifiers or receivers rated between 15 and 200 watts.
Floor bounce occurs when sound waves reflect off the floor and interfere with the direct sound from the speaker, often causing a muddy midrange. This feature is engineered into the crossover to counteract those reflections, ensuring the vocals and instruments sound more natural and precise.
Yes, the speakers are designed to look clean and professional with or without the grilles. The Secure-Lock system ensures the grilles stay firmly in place when attached, but they are easily removable if you prefer the aesthetic of the exposed aluminum drivers.
With a frequency response reaching down to 41Hz, these speakers provide a solid amount of bass for music listening in smaller rooms. However, if you are building a home theater system or prefer deep, cinematic low-end impact, you may still want to add a dedicated subwoofer.
