3. At a moderately loud level, play music or a video soundtrack with extended bass that is repetitive or
continuous.
4. Walk around your room and note where the bass sounds good and where it sounds boomy or very
quiet. Note that “good” does not necessarily mean “loudest.” Good bass should be clear and have
well-defined notes, if you’re listening to music (which we recommend).
5. You should find more than one location that sounds good. Placing the subwoofer(s) precisely at
these locations generally results in good bass performance at the listening seat, assuming it is in an
aesthetically acceptable location.
6. Re-position the subwoofer(s) as described above and switch all speakers back on.
The preceding is only a guideline. You may want to use a bass test disc and SPL meter to more
accurately determine the bass characteristics of your listening room (see your AGA dealer for more
information). Remember that room acoustics vary, so it almost always takes some experimenting with
placement to achieve best performance. The result will undoubtedly be better system performance and
lots more smiles per song and movie.
Below are some links to sources for free test tones and test-tone generators. If you can’t connect a
computer to your system as a source, you can record some of these test tones onto a CD or DVD using
your computer and then play them back in your system. Use extreme caution when playing these test
tones by always turning down the volume completely before you play them. Bring up the volume
gradually and within reason.
There are also links to a couple of inexpensive SPL meters that were available at the time of this writing
which can be used to set levels properly in your system. For more information on how to set levels
using an SPL meter, please see our website.
