The maximum distance in Creative's THX control panel set at something like 7 and half feet. This seems stupid to me. Is there any way to make this distance larger? Does this affect the sound when I'm using Dolby Digital Live? I assume it does since DDL's output seems to take on all control panel properties. The seating position in my home theatre is approximately 12 feet from the front lefts and the surrounds, 11 feet or so from centre. I did not place the surrounds, which are ceiling mounted. I've got my HTPC hooked up to an older reciever, the Onkyo DR s2.0. I'm using Dolby Digital Live to encode all audio to Dolby Digital, and sending it to receiver over optical (coax cable not long enough).
