I also would say that it is very hard to approximate a "headphone Sound Signature" in a dynamic room speaker, and almost certainly not at $1K with the furniture a bedroom has in it. None the less If I were you I would listen to as many speakers as I could, to get an idea of what is available, at what price, and size etc.
That said,you may want to try a panel speaker with a sub woofer, to approximate a Sennheiser sound. I own HD 700s which I understand are much less bassy than the 650s.
