TweeterLevel Switch doesn’t merely reduce the high frequencies (like other in-walls); it allows you to “notch out” the frequency range from 3500 Hz - 6000 Hz where    room acoustics and some recordings can be harsh sounding. We leave intact the last octave over 10 kHz where the nuance and emotion of the music and movies are conveyed.

Wall Distance ToggleSwitch providesmaximum placement flexibility without performance loss by tailoring the frequency response for an installation placement near a corner or adjacent wall. Like the Tweeter Level Switch, it “notches out” the range from 80 Hz - 150 Hz in the mid bass where adjacent wall or ceiling reflections can add “boominess” or exaggeration while leaving the deep bass response intact.
