Thank you for bringing this up. There is a lot of confusion about the use of the Theater Inputs. We recommend the Theater input ONLY in two situations:
1) You need additional dynamic range for HT use . . . the Theater input is NOT recommended for two-channel music use. In fact, rarely is it needed for HT use. The main reason it is there is:
2) IF you want to have the sub used at the same type in a dedicated two-channel setup using the left and or right inputs, and then the Theater input can be used for the HT input. In this way, the two systems can be adjusted and calibrated separately. The HT processor controls the sub level for HT, and the sub level for two-channel is controlled by the subwoofer level control.
After reading your post, I went back and edited the description of the inputs/filters on the Force and Titan page. I hope I've clarified. Please let me know if there are more questions. Once again, MOST of the time we recommend either the left or right inputs (or both), rather than the Theater input.
