Well then they might work, the trapezoidal shape is an advantage, and I forgot, but I believe the front baffles are canted inward so that the back of the speaker is flat on the wall but the front is toed in towards the listening position. That also will help on the side reflections, but you might have to adjust the width of the speaker placement or your listening position to account for that toe-in. Still wonder about the extra bass, though, as the 3.3s had tremendous bass extension, one of their strong suits. Any way the owner/dealer can let you try them in your room? Or maybe you can set them up near corners where you go to hjear them to see.
Anyway, I'm only speaking theoretically, hope some NHT owners can add their experience.
