I'm thinking about putting the VP180 and EP800 behind an acoustically transparent screen. This would result in the VP180 about 2" from the wall and the EP800 with almost no room behind it. Two inches is a lot closer then I'd normally consider for the a speaker with a back port. It might be ok... bet a lot of vp180 are running it that way. The EP800 is probably ok up against the wall (no port) but I kind of wonder if it's an limitation which I might regret acoustically.
