Of primary concern was a speaker that would be spectrally balanced throughout the room rather than only in a very narrow and defined “sweet spot”. The SR-2 was specifically built to those parameters.

Once the speaker position and cabinet tilt is optimized for apparent tweeter height the listener will need to adjust the level controls for optimal results. In a symmetrical room, the adjustments for left and right cabinet would be identical, asymmetrical rooms may require disparate settings of level controls or left and right speakers. Optimal level settings will be arrived at only by careful listening to a variety of source material while making small adjustments. Avoid setting that enhance only one select recording

On the rear of the SR-2 cabinets are 2 level controls. One level control on the woofer and one level control on the tweeter. All controls are 3 position switches that select fixed values. Mid position is considered “Normal”, UP (clockwise) increases the level of the drivers associated with a control. DOWN (counter-clockwise) decreases the level of the drivers associated with a control. Conditions indicated clearly at each switch by + /- silkscreen logo.

The level control on the woofer controls the lower bass and 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 upper of the two level switches, selects one of three tweeter levels. Mid position typically for neutral rooms, up or clockwise for
