802d or 800d

Hi I have the chance of owning either of these speakers for the same money.Is there much difference in performance.I do like the look of the 802ds but they look a bit laterally unstable so may go for the slightly bigger 800ds.My room size is 28 feet by 16 feet.Using vdh fevelation hybrid chord 1200e qbd76 blu transport.Will probably upgrade to a more powerful chord amp soon though.
