4) The Subwoofer Location Test file contains pink noise that is routed to the front left and front
right speakers for the duration of the test. Another signal is fed to the LFE channel that
alternates between off and pink noise in 4 second intervals.
If the front pink noise image shifts at all with the subwoofer on, or if you distinctly “hear” the
subwoofer’s location, you will have to: a) reduce the subwoofer crossover frequency, b) move the
subwoofer, or c) reduce the subwoofer level. Before repeating the listening test, you should rerun your
system setup routine.
Final Thoughts
Problems usually arise when the home theater space forces a violation of the setup recommendations
outlined in this document. We recommend setting up the system and evaluating the setup for several
weeks using suitable source material. During this time, take notes about things that do not sound
natural. Try to confirm the behavior with different source material since the recording itself may be at
fault. Once you have documented and confirmed any system weaknesses, try moving around the room
to different listening positions to determine if the artifact gets better or worse. This may provide clues
as to the source of the problem. Start by making small adjustments to potential offenders. Tilting and
toeing speakers differently can often make a significant difference. See our Troubleshooting Guide for
additional suggestions.
You should re-evaluate the system setup after you have lived with it for a few months. As you gain
experience listening to your new home theater system, you will start to recognize characteristics that
were hidden within the overwhelming details of a new system installation.
