If you want to use the ”Crawl Test”, do so before performing any of the optimization methods.
Room placement is one step to equalize the subwoofer(s) to the room. Subwoofers operate at extremely low frequencies, which are primarily
omni-directional. Hence; you can’t usually tell where the bass is coming from. Finding the best location for your subwoofer in your room is a
trial and-error process.
With the ”Crawl Test” Technique:
• You find the best tradeoff between appearance of the subwoofer in the room and the subwoofer sound quality.
• You optimize the subwoofer placement when the room is in the configuration that it is in when you typically listen, such as doors opened
or closed, curtains open or closed, etc. Additionally, you can learn what effect the configuration has on bass quality, by changing it and
listening or measuring.
• You can rely just on what you hear to pick a location or you can use the microphone and sweep tone with the subwoofer set to Manual
EQ to look at the frequency response graphs to see which location is best.
Your satellite speakers also contribute to how your audio system sounds. If moving your satellites is an option, you might likewise place them
through experimentation and measurement.
