Location
Placing your Sunfire Subwoofer in a corner of your room will produce optimum performance. Experiment with at least two corners and then decide which is the best.
Although low frequencies are non- directional, factors such as room reflections, standing waves, resonance and absorption strongly affect your subwoofer’s performance.
Moving the subwoofer from one corner to another can have a major effect on the bass response.
Remember to keep it at least two or three feet away from
any TV screen, computer, VCR or magnetic tapes and
discs. This will reduce the chance of the magnetic fields upsetting the TV screen or erasing your magnetic media.
Also position the control panel so that it is not touching anything and can receive good ventilation.
Using Two Subwoofers
If you wish to use two woofers, the sound output will double (an increase of 6 dB). Locate the woofers with one in each corner and experiment with the location and phase control to achieve the best bass response.
Always drive each woofer through the Left/Mon input even though you are driving one woofer with a right channel drive and the other with a left channel drive. If your preamplifier has a single sub/LFE output, use a Y cable to split it into two outputs.
