When my subwoofer kicks in, it sounds far too soft. I am using a Denon 2802 with Mission M72 speaker package. As advised by Mission, I set all my speakers to "small" and the cross-over frequency to 100 Hz. I set my 70W subwoofer volume to between 2/3 to 3/4 way and the subwoofer level on my amp is -2DB. However, when the T-rex in JP3 stamps his foot down, or in other scenes/films when the subwoofer kicks in, I feel the vibrations but the overall sound (from all the other speakers) is very soft. If I turn the subwoofer down, the over sound sharpens but I lose the subwoofer effects (vibrations). Any suggestions to what I'm doing wrong and how to fix them, I'll be most grateful for. Thanks.
