Fine-tuning

To facilitate proper set-up of your speakers in a variety of room situations, we have included several heavy duty toggle switches on the terminal plate, located on the back of the loudspeaker. All switches in the “up” position represent the “anechoic flat” position.

Switch 1: can be used in the “down” position to provide a warmer sound by shelving information above the 400 Hz by 2 dB. This can be helpful in restoring system balance with closely miked program material or near field listening positions.

Switch 2: can be used in the “down” position to reduce edginess in the lower treble region due to room flutter or bright program material.

Switch 3: is a low frequency impedance contour when using amplifiers with high current capability. It can be used in the “down” position to reduce upper bass heaviness caused by standing waves (typically the frequencies around 65 Hz, excited by the floor/ceiling interaction).To increase bass impact leave the switch in the “up” position.

Switch 4: can be used in the “down” position to defeat the rear-firing ambience tweeter.
