Getting The Most From Your Subwoofer

Positioning your Subwoofer

The positioning of your subwoofer will affect the quality of its performance. For example, locating the subwoofer near the wall will increase bass response. If the subwoofer is incorrectly placed it can sound "boomy", especially if it is too near a corner. It is worth experimenting with speaker positioning and controls (as explained in previous sections) to find the best balance of bass quantity and quality. A "boomy" sound delivers particular bass notes in the musical scale unexpectedly louder than others.

Variable Notch Filter Setup

If, after experimenting with the subwoofer position, you feel you still have a “boomy” sound then the notch filter will be able to attenuate the particular bass note, or frequency, where the “boom” occurs. You will need to use the supplied EQ Test CD, containing 11 special test tones. One of these tones should highlight the “boom” you are hearing. We recommend the accurate measurement of the test tones using an SPL meter, rather than just listening to the tones, though this can be attempted as follows:

If you can clearly hear one tone on the CD to be much louder than the others, the following steps can be taken.

Run the CD test tones to check for any loud problem tones. After locating the loudest problem tone, repeat on the CD and using a combination of the notch filter ‘cut’ and the ‘frequency’ control tune out the problem frequency, so that it matches as closely as possible the sound level of the adjacent test tone tracks.

Understandably, a much more accurate adjustment can be acheived with an SPL meter, which can be purchased from a good electrical store. To do so, follow the instructions below:

1)Position your subwoofer in its intended location (as discussed above), ensuring the notch filter is set to the OFF Position. Diconnect all other speakers in your system.

2)The SPL meter weighting should be set to C–weighted and the response time set to slow (if applicable).

3)The supplied test CD contains a reference tone, plus 11 modulated tones, each covering a narrow frequency range. These values correspond to those in the table provided.
