    I've spent more money on speakers over 60 years of listening to music than most people have any right to do. I've owned a dozen or more bookies over my life and the B50s are the real deal. They are amazingly musical, very dynamic for their size (if you're using decent amplification such as Bryston, NAD, Rotel, even my 10 watt Class A tube amp), and fill my 12' x 15' bedroom with imaging that is deep, wide & high. Musically they sound pure, sweet & are as near to tonally accurate as anyone has a right to expect at this price. B50s can even reveal any weaknesses in your musical source material and your supporting equipment! For the money, it just doesn't get any better. Absolute wizardry IMHO.

    Sounds good, very clear, but not dinamic enough.
