I will have to be one of the dissenting opinions here.
While they are certainly pleasant to listen to, they are hardly accurate, detailed, nor do they image or create a soundstage with any real proficiency.
I have heard them out in the room, and very close to the wall. There was an improvement out in the room of course, but sill not great. It's hard to get around the inherent problems with wide baffles.
And I don't care what they say, 'controlling resonance' of the enclosure, is not as good as trying to eliminate it.
That being said, they do sound better than just about any other 70's 'heritage' speaker I've heard. And that lush midrange, makes vocals sound pretty impressive.
