Right on about the 1-2 foot move.

My 2 cents: as long as you aren't going about 70% on the level out of the receiver, you shouldn't notice any problem with the sub signal. They are designed to be operated in that range, but can start to sound bad when you crank up the gain/boost above 70% (as a general rule).

I've got my audssey sub setting on +8db out of a limit of +12db, so that's about 67% (ignoring the log scale) of the signal boost and it sounds fine. It's going to a powered sub.
