Wiring and Connections

IMPORTANT! Wiring Precautions

●

Ensure that the positive (+) and negative (-) bare wire or spades DO NOT touch when connected to the binding posts as this will short out the amplifier

channel.

●

Ensure that the appropriate polarity is maintained from amplifier to speaker to ensure proper phase for both speakers.

Controls and Adjustments

This speaker features a HF level control that can be used to adjust the HF

level independently from the level of the woofer. The default setting of 0dB

represents a flat balance between the woofer and tweeter, however in some

cases there may be a need to adjust the level of the tweeter.

●

For rooms where the high frequencies sound bright, lower the relative HF

level by turning the knob counterclockwise.

●

For rooms where the high frequencies sound dim, raise the relative HF

level by turning the knob clockwise.
