Know before you buy
These speakers are compatible with amplifiers ranging from 20 to 450 watts per channel. Given their 4-ohm impedance and 92 dB sensitivity, they are relatively efficient but will perform best with a high-quality amplifier that can maintain stability at lower impedance loads.
Yes, the Motion XT F100 features dual binding posts that support both bi-wiring and bi-amping configurations. This allows you to separate the high and low-frequency signals for potentially improved clarity and control.
The tool-less adjustable F.A.S.T. Outrigger Feet provide a wide, stable base to prevent tipping while decoupling the speaker from the floor. This isolation helps minimize unwanted vibrations, which results in cleaner bass response and improved imaging.
This tweeter uses a thin-film diaphragm that moves air much faster than a traditional dome tweeter. This design provides exceptional high-frequency detail and clarity while significantly reducing distortion, even at higher volume levels.
With a frequency response reaching down to 31 Hz, the F100 provides substantial, deep bass on its own for most music listening. However, if you are building a dedicated home theater system and want to feel the lowest sub-bass frequencies in movie soundtracks, adding a dedicated subwoofer may still be preferred.
While the Folded Motion Waveguide helps control sound dispersion, it is best to place these speakers at least a few feet away from side and back walls to prevent bass reinforcement from muddying the sound. Experimenting with toe-in toward your primary listening position will help you dial in the best stereo imaging.
