I agree with the Wolf - Use your ears. I tried using a test cd with tone sweeps to blend in my Rel with my speakers. Once I got what sounded like a perfect blend the bass was severely overpowering once I started playing music.
Whats a good freq to measure baseline SPL when calibrating a sub?
So I finally got my REL T/5i sub and will be calibrating it this weekend. I have an SPL meter and a test tones CD. I know the first step is to pick a test tone to set the baseline SPL from my monitors which I will use to compare the low freq response of the sub. Can someone please recommend a good starting freq?
