    to make a long story short, I had used the avia disk and rat shack meter to do a front left frequency sweep, which uses the sub at 120hz and under. The biggest issue was a 12db bloom at about 57hz.

    I loaned out my avia disk and borrowed the sound and vision guide to home theater from a relative.

    Anyhow, I had moved my subwoofer to the other side of the room and ran the S&V "crossover" test... from the description it sounded like it was simply doing a frequency sweep.

    Is this essentially the same thing as the avia disk was doing when I did the frequency sweep there? The reason I ask is that that major bass bloom I was getting around 57hz is gone. Now, it's hard to tell because the S&V disk doesn't show the numbers as it is doing the sweep, but I definetly didn't have a 12db spike. The biggest spike I did have was about 4 db. Which is livable.

    Just burn a few test tones to a CDR and play them in your DVD player at the frequencies you want.
