Has anyone here heard the dual CS5s used to create a dipole? I remember Jim Thiel saying that putting two CS5 pairs back to back would provide greater listening improvement than bi-amping the beasts.
I ask because I've recently been playing with my new toys, a Bose 901 II system. And while I've just taken the conversation from the sublime to the ridiculous, I have to admit that these little beasts sound a lot bigger and better than they ought to: they're not the most accurate speakers in the world but they are a whole lot of fun. And I also found that the music is far less of a blurred mess than intuition would suggest.
In a moment of insight or madness, I realized that the 901s are a highly equalized single driver system. Not sure if that would make them time and phase coherent but there is no crossover to throw the signal out. And I know that the 3.5s were phase coherent and used an equalizer so the 901 EQ wouldn't necessarily cause phase issues.
This makes me wonder if phase coherence wasn't part of the secret sauce that made the 901s work in the first place. The end result isn't a jumbled mess, it's a pretty impressive Technicolor rendition of the signal. And if I'm right, two pairs of CS5s would give you that signal in Technicolor and 8k -- although you'd be spending a whole lot more on amplification :)
