I bought a pair of the r645's about 8 months ago. Personally, I love them. I've had no problem placing them. They present great clarity and detail, a wide soundstage if not the deepest and good top to bottom tonal balance. I've recently heard other speakers, one nuveau horn design and one well known all ribbon design both of which cost considerably more. I'll keep the newform's. Hope that helps.
