Know before you buy
These speakers are quite versatile and work well with amplifiers rated between 15 and 200 watts per channel. Since they have a 5-ohm impedance, they are compatible with most standard receivers and integrated amplifiers rated for 4, 6, or 8-ohm loads.
The F1 is specifically engineered with Controlled Dispersion technology and a Folded Motion Waveguide to minimize unwanted reflections from your walls and ceiling. This helps maintain a clear, focused soundstage even in rooms that aren't acoustically treated.
Yes, the F1 is designed as a compact floorstanding model, making it an excellent choice for smaller spaces where you want high-performance audio without the footprint of a massive tower speaker. At just over 8 inches wide, they fit easily into most room layouts.
This tweeter uses a thin-film diaphragm that moves much faster than a traditional dome tweeter, resulting in significantly higher clarity and detail in the high frequencies. It provides a crisp, natural sound that makes vocals and instruments feel more lifelike.
The grilles are entirely optional and use a secure-lock mechanism, so you can easily remove them if you prefer the look of the exposed aluminum drivers. They are designed to be aesthetically pleasing either way, so the choice comes down to your personal style preference.
Floor Bounce Compensation is a design feature that adjusts the speaker's output to counteract the sound waves that reflect off the floor. This prevents the 'thin' or 'hollow' sound often found in floorstanding speakers, ensuring your music sounds full and balanced.
