Well to be fair I did say I get it to a degree. I've not had the chance to hear the universal versions of the UE10 and UE11, regardless though, those are not really what I was referring to. Listening to Triple.fi's or E500's I'd put the SA6's and Image X10's in the same league and to me anyway the differences are more preference based than those that would be attributed to multiple drivers. I'm sure in some respects it's easier to cover a full range with multiple drivers but it also introduces other issues with crossovers and such.
