Hmmm...maybe my wording was a bit confusing.

Re-directed bass = RDB.
LFE (.1 channel) = LFE.

With fronts set to large:

"Sub = LFE" means LFE sent to sub, RDB sent to fronts.

"Sub = L/R+Sub" means LFE and RDB sent to both sub and fronts.

Is there any way to have the fronts set to large and have the LFE + RDB sent *only* to the sub?

Thanks,
