Calibration Help (1 Viewer)

I read all of the thousands of other posts about peaks at 80hz or a dip at 500hz, how the hell do find that out? What do I need to see how my system is, how do I fix it? Thanks for all the help.

Chris, go to the Speakers/Subwoofer section and search for "BFD" or "House Curve". You will find lots of posts.

Basically, you get at disk that puts out sound at 20 hz, 30 hz, 40hz, ... up to about 120 hz and use a sound meter to measure the volume.

In a perfect room, you would get the same volume for all frequencies. But because of wall-reflections, you get peaks and dips at some frequencies because of additions/cancelations of wave patterns.

You can also get RTA - Real Time Analysis software for your PC that outputs the tones, and measures the response to create some of the nice charts you will see in the Speakers/Subwoofers forum.

Also do a search on "House Curve" for more advanced discussion.
