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. 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. 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. The limited bandwidth pink noise is -3dB less than my other speakers which measure at 67dB after I have calibrated them using the full bandwidth to set them to 75dB. I have read that the subwoofer is -3 less on the disc. The speakers are set to small. Am I done or is there something that would require being done differently?
