802D3’s have a more overdamped bass alignment and less energy through the upper bass and lower mids, so they are by design a less warm / rich sounding speaker than the 802D2 or 800D2. Positioning them closer to the room boundary might be beneficial, and ditto less toe-in to the listening position, for a fuller, warmer sound, but the basic characteristics are different enough that it would be difficult to make one sound exactly like the other without the use of active room correction.
Fwiw, I use 800D2 in a mid sized room, with room correction below 100Hz to fix a mode at 40Hz.
Best axis for listening in my experience is just below tweeter axis, and this applies to all 800D,D2,D3 models. Listening at the level of the FST results in a loss of presence region energy. (2dB dip at 2kHz)
