 I setup my MP3+ USB external sound card and saved the file, setup my RS digital SPL meter with the subwoofer at 75, then I turned up the volume on the Crystal Acoustics subwoofer a few dB to 85 and took a measurement. |
Why?

I did not check the C weighting because I had the RS meter file loaded. I added some filters to what REW suggested and optimized the peak and gain. This is location in my room that gives the most overall smooth response. I was not able to measure with a crossover since my receiver is being repaired.

So you don't have an AVR in the loop? Are you using computer to BFD to sub?

I moved the crossover up on the graph.

I measured after applying the filters without adjusting subwoofer volume on my HD-DVD copy of DVE with limited bandwidth pink noise to be 64dB.

I understood you are using REW, Why are you mixing with DVE now? Limited bandwidth can yield different results from full bandwidth... But again why aren't you using REW sin sweep from say 10 to 200 Hz to test subwoofer FR?
I think either you or me are missing something. Sorry for my questions, but if you reply to them we can try to figure out what the required is.
