Please Read: Getting Graphs Ready To Post
It will help tremendously if we all have a standard to compare graphs... please adhere to these guidelines prior to posting your REW graph... Thanks!:T
The preferred axis for ALL subwoofer graphs is:
VERTICAL = 45dB-105dB
HORIZONTAL = 15Hz-200Hz.
The preferred axis for full range graphs is:
VERTICAL = 45dB-105dB
HORIZONTAL = 15Hz-25,000Hz.
These values are defaulted into REW, but can easily change and must be set back to these axis for posting graphs.
Setting the axis limits and image size for your graphs:
Adjust/set your graph axis limit... click on the Graph Axis icon button in the top right corner of REW as shown below.
A form-fill will pop up to enter the preferred values.
Each time you click this button the value from your last entry will be available and a simple Apply Changes loads them.
Ensure your graphs are set to logarithmic instead of linear.
Click the Feq Axis icon button in the top right corber of REW as shown below to switch between LOG and LIN graphs. Use LOG as shown in the examples below.
Correct logarithmic graph:
-------
Incorrect linear graph:
-------
Smoothing:
Smoothing should not be applied to subwoofer graphs. For full range graphs, 1/3 or 1/6-octave smoothing is beneficial.
Setting your graphs image size:
For graph image size... 800 pixels wide is the normal limit for the forum.
To create the graph image you will click on the floppy icon in the lower left corner of your graph as shown below.
Ensure the width is 800 and then save your graph image to a folder somewhere on your computer and upload it to your post.
To learn how to upload your graph to a thread post... see the Posting a Graph thread.
In the next posts to follow, the method of posting graphs created with the Excel Manual method of measuring frequency response is discussed, as it is a bit different than creating graphs with Room EQ Wizard. If you are using REW, it's not required reading.
