I just got an SPL meter to measure how loud my speakers were. To my surprise, they were all at their correct levels, but when I set the subwoofer, it's TOO low for movies, and WAY TOO low for CDs. I set all of them at 75 DBs. Someone said that the receiver automatically adds 10 DBs to the bass, but mine is not obviously doing it. Is it ok to do all speakers 75 dbs, and 85 dbs for the sub?? How does everyone else have it set? By the way, I'm using Video Essentials to set the sound.
