Since we are on the subject of speaker drivers, are the drivers in the Onwall Gold surrounds similar to those used in the OnWall Silver surrounds? If one were to use a pair of Onwall Gold's on the sides and Onwall Silver's in the back (with Gold LCR's up front), would that provide a farily seamless surround field? In my particular situation, I think doing Gold surrounds in the back would be overkill, but I still want a "presence" back there.
Matching side surrounds to rear surrounds isn't all that important for two main reasons. First, dipoles have a diffuse sound, anyway, so they don't have as identifiable of a sonic footprint. A good deal of the sound that reaches your ears is, by design, reflected. The other reason is no direct sound from rear surrounds will directly enter your ears, unless you have some really weird ears. Like ears that are mounted backwards.
That said, the rear surrounds don't have to have the same capability as sides in most applications. And while the Bronze and Silver Surrounds use very similar drivers, the drivers in the Gold Surround are entirely different. The Gold Surround is (if this is possible) a spectacular surround speaker.
