If you own a Denon THX amp like the A1SE (as I do) and the the KEF THX speaker package I'd like to know what your speaker level settings are. The sub has a THX mode setting that is supposed to let the amp do the crossover bit, and sets the output level match the amps sub out. However with the KEF THX package and all speakers set to 0db, all speakers 'small' and the sub in THX mode, the sub level appears to be way to loud. If I leave everything on 0 db and watch an action DVD, the sub almost blows itself apart with the LFE. I've ended up setting the sub to -12db, and the other speakers to around +2db. That's a 14db difference which seems wrong for a complete matching THX setup. I know the Denon/KEF THX partnership is popular one so there must be loads of people here with experience of this. How is yours set up?
