Placement and Positioning
- Before deciding where to place your speakers, survey your room and think about placement, using the illustration as a guide.
- Avoid placing the speakers near power amplifiers, heat registers or other objects that generate large amounts of heat.
- Avoid placing speakers in humid or dusty locations.
- Avoid placing speakers in direct sunlight or other intense light.
- Refer to the illustration for distances from walls, between the speakers, and angle to the listening position.
- The speakers should be raised so that the tweeter is approximately at ear level. The JS-120 or JS-150 speaker stand (sold separately) can be used to achieve the proper listening height and angle.
- Angle the speakers towards the listening position closer to the listeners ears for a stronger center image and away from the listening position further from the listeners ears for a more spacious image.
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 level controls that can be used to adjust the level of the mid-range driver and tweeter independently from the level of the woofer. The default setting of 0dB represents a flat balance between all three drivers, however in some cases there may be a need to adjust the level of the tweeter and/or mid-range driver.
Mid Frequencies (MF Level) Adjustments
- For rooms where the mid frequencies sound more forward, lower the relative MF level by turning the knob counterclockwise..
- For rooms where the mid frequencies require more presence, raise the relative MF level by turning the knob clockwise.
High Frequencies (HF Level) Adjustments
- 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.
