AudioKinesis Prisma
or AudioKinesis Rhythm Prism
are a couple designed for it. I have heard the latter in a small room and they were good. I do not know what you have been reading, but there are a variety that will do fine against a wall. Easy examples: the ones I own (sealed three-ways) sound better in a Cardas room config but are perfectly enjoyable against a wall. Robert Lee told me his Crescendos should be placed under two feet or over five feet away from the front wall.
Speakers will sound better when no placement variables are fixed but most of us have some constraints still and do okay.
