excerpt
"THREE-POSITION ACOUSTIC BALANCE SWITCH The selector switch is located on the back of each loudspeaker and provides the user the ability to tailor the output above 400Hz. “HI” Position – This is the default position, or 0dB. This is the preferred selection for neutral to dead listening spaces. “MID” Position – This adjusts the loudspeaker -1.5dB above 400Hz. Use this setting for slightly live listening spaces. “LO” Position – This adjusts the loudspeaker -3.0dB above 400Hz. Use this setting for very live listening spaces (for example, a room with a tile floor). Of course, the selection is up to the user, and the user may want to experiment in order to determine the best selection for their particular listening taste. Please remember to set both speakers to the same setting, otherwise a poor center image will be the result."
