what is the best position for pendragons

I would put them where they sound the best to your taste.

It's the room not the speakers. Your new speakers will end up in about the same place as your last speakers. Where other people have placed their speakers means nothing. You have to do this on your own.

Yes, I understand the individuality of each room; moving and discovering that "best spot" is half the fun. But I was asking in general terms for the Pens what one would expect because of their size ( or any speaker for that matter). In a 20x20 room I won't be able to move them 5' from the wall and I might have to consider a different speaker even though the Pen reviews sound great.
