Note: Do not place the unit near a heater or forced air outlet, as this may impair the ability of the internal amplifier to dissipate heat. It may also harm the finish.

When you’re setting things up for the first time, you will need to adjust the bass level control to keep the bass volume the same for various subwoofer positions. The only way that you can make sure that you’re not being impressed by more bass, instead of smoother bass, is to keep the volume the same for all subwoofer positions.

Begin with the low pass control set to 80, adjusting a little at a time to give the smoothest transition between the subwoofer and the main speakers as, for example, a bass guitar or cello is played up and down the scale. Try both positions of the phase invert switch, as unusual room acoustics may be present at the crossover frequency. Again, some experimentation will be needed to find the best setting.

Once the controls have been adjusted so that the sound is balanced between the subwoofer and the main speakers, you can leave them alone. Minor differences in the source material can be compensated for with the volume and tone controls on your audio or audio/video electronic components.

Fine Tuning

Atlantic Technology subwoofers integrate easily with virtually all other brands of loudspeaker. The adjustable low pass filter and versatile hookup options make it a snap. With proper placement in your room, this subwoofer will supply a solid foundation to any audio or A/V system.

For best results, we suggest that you “tweak” the controls and cabinet position slightly over a period of time (1-2 weeks), as you become accustomed to the sound, and have the opportunity to hear a variety of music and/or movies. Remember that a small adjustment may have a large overall effect.
