So last weekend I finally got a RS SPL and attempted to test the response of my subwoofer, however, an error message popped up every time telling me I had to much head room. The volume was not great enough? Then yesterday evening I tried the same setup and found that the volume was too great.

I am using an X-FI Xtreme Music sound card and the line in is the same as the Microphone, I think, but have read in numerous posts that the Microphone jack is not suitable for testing when connecting the SPL out to the sound card.

More or less I have been reading for a couple of days now trying to figure out what I am doing wrong and was interested in knowing if the Sound Card could be the problem.

Also should I be hearing audio from the L/R channels when testing the subwoofer? Or could I only send sound to the subwoofer using the analog input on the back of my AVR?

Thanks to any who reply. I am very new to this so please bare with me.
