Moved Subwoofer

I found a program called ToneGen today that lets you create a few different types of audio tones and custom frequencies. I generated some tones and burned them to a CD to test my subwoofer placement. Turns out my placement was pretty bad for the 20Hz range. I had a significant dip there. So I placed my subwoofer in the primary listening seat and used my Radio Shack Digital-Display Sound-Level Meter to identify a better location on the inside of the left main speaker. This fixed the 20Hz range dip, but I still have a major 80Hz dip.

I'm going to perform some additional testing with new 1/6 octave tones I just generated. To find out the proper frequencies in terms of octave fractions, I used the standard octave bands information from Prosig. I have sixty-six 1/6 octave tones starting at 10Hz to 20kHz at thirty seconds each. Should make for a good test CD.
