If The Reciever and sub both have crossover settings, should they both be set the same? Should the sub stay set at a certain point and the adjustment done with the receiver or vice versa? I've been leaving the sub adjustment at halfway and using the receiver to adjust, I set different for TV and movies, but haven't been very impressed with the results. My room isn't a very good set up for 6.1. It's a Yamaha receiver and sub.
