Because there is a stage lip I would tend to go higher
Also where does the baffle wall end
Also I find it very odd that you have all this clipping as that I hve never seen in a room that THX designed

Gordon,

1. Tha baffle wall end on the stage. Is this answer to your question?
2. Clip: do you want a photo? This time THX erred... I'm absolutely sure that EQ and all levels are correct.

The R2 does not measure subs on a numeric basis - regardless of what weigthing you apply you should always set subs on a RTA - you know the score, flat for optical and +10 for Digital or Mag. The R2 (in THX mode) only looks at the sub between (I think) 40 and 100hz, and then decides a pass or fail. OK, practically this always reads around 91db as it does on an Abacus.
