level of the drivers associated with a control. DOWN decreases the level of the drivers associated with a control.

The level control on the woofer module controls the mid-bass level in the room. This control should be adjusted to optimize bass

in room while minimizing undesirable bloom and boom of low frequencies.

The two level controls of the upper cabinet are somewhat unconventional, having been designed to address less than ideal speaker positions in less than ideal rooms, specifically the average domestic environment. The upper of the two level switches, selects one of three tweeter levels. Mid position typically for neutral rooms, up or counterclockwise for rooms which are otherwise lacking in high frequency and down or clockwise for rooms which tend to sound too bright.

The lower of the two level switches adjusts the spectral balance between the upper cabinet and the lower cabinet. This control affects both tweeter and midrange drivers equally, raising or lowering the overall level of the upper cabinet in relation to the lower cabinet.

If the listening room allows the listener to be directly on axis with the drivers and the room is neutral in character then the most likely setting of this control will be either the mid position or perhaps the clockwise or lower position. Rooms that require the listener to sit off axis to the speakers and rooms that have a surfeit of absorptive surfaces frequently require this control be in the up or counterclockwise position. Rooms that sound bright and those with a multitude of hard reflective surfaces typically require this control be set in the down or clockwise position.

The suggested settings are just that… suggestions. There is no substitute for listening and personal judgment. We encourage users of this product to experiment with level settings and fine movements of speaker position until the most accurate or pleasant combination of spectral balance and soundstage are achieved.
