the 950 does not allow seperate distances for each surround speaker. It only allows you to set the distance for front/center/surround. In the case of the surround speakers, the set distance applies to all 4 surround speakers (if so equipped).
Some receivers/processors do allow seperate distances for each individual speaker.
With a dipole speaker the distance setting is unimportant. Properly installed, a dipole should surround you with a diffused sound. If one speaker is closer than the other, simply matching the output levels will be enough to compensate.
