Hello,
If you are using your subs for music please run your front or L/R speakers full range and set the limit on the subs crossover to meld with your speakers. You might be surprised going all the way up to 110hz on the subs crossover for music or melding with the front two speakers. When watching movies it is a different setup they tell you to do. I do what sounds best. Even my very small surround speakers play down to 60 hz and my center plays down to 45 hz. I set the fronts to large or full and the rest at 60hz. My ported sub comes in at 80 hz to blend in. My main speakers play down to 25 hz and my subs are set to roll of at 50 hz. This is the frequency when I could tell when they disappeared.
