Placement of Subwoofer

Setting up EQ or the Room

Play some familiar pieces of music that have prominent bass lines. Start with the EQ switched out and then adjust the EQ filters one by one switching the EQ in and out. It is better to start with the EQ cutting the frequencies and not boosting them. Remember that a 10 dB boost is adding ten times the power at that frequency so it would be easy to overload the system at high power levels with the EQ sliders set at maximum.

Room Size and Room Position

The size of the room and the position of sub-woofer placement will also determine low frequency limit of the subwoofer. So by adjusting the EQ settings, the ideal response can be obtained without having to place the subwoofer in an unpractical location. Small rooms usually add gain to low frequencies, which can be overpowering to the rest of the music. Large rooms need greater low frequency energy to sound balanced. The EQ settings can be adjusted to fit the room size. The 5 band equalizer should be used with great caution. The power levels to the speaker can be boosted by as much as 10 times! So if the subwoofer is running at 100 watts the EQ boost at maximum will try to push the amplifier to an impossible 1000 watts! Although the amplifier and speakers are designed to handle overload conditions it is still possible to cause damage from mis-use.

The subwoofer can be placed virtually anywhere in your room without affecting the stereo image of your main speakers. Placing the unit in a corner of the room will yield the greatest bass output but may not provide the best sound, as this position will cause maximum room mode resonance. You can start with this position and then move the subwoofer to different areas until you find the sound satisfactory. The best method is to try different positions. Keep a clearance of 100mm/4” from the wall or furniture to provide best performance.
