The Wilson Cub speakers are meant to be used with Puppy V.Ior Whow3 subs. The rest of the reviewers who have experienced the harsh or even bright side of this speaker should go to any dealer near you and try them with Puppy V.I or Whow3 setup then you'll see what I mean.

I went shopping in search of a smaller speaker that could give me clean, open beautiful music. I found a pair of Wilson Cubs. I have never ever heard speakers like these. It was an epiphany. The system was Theta transport and d/a with a Reff Rowland Concerta Integrated Amp (85W). BTW- very $7600 worth of electronics.
The clarity, the imaging were to die for. However, the most remarkable aspect of these speaker was their ability to reproduce the full range of music at any volume. This may seem trivial, but I can't tell you how often I play music at a volume that is louder then I would prefer because the sweet spot for the speaker requires that extra db. These speakers have no such problem. The full range is on tap from the moment the music begins. Turn the cubs up and look out. The same dynamic range, just one hell of alot more music.

Of course $6000 plus stands is a big pile of money for monitors, but these may be the last pair of speakers I ever buy. I haven't bought them yet, but I plan on doing a load more of listening and I can't wait!
