Summary: Very neutral and precise speakers at any volume. They don't enhance the sound of music that was recorded poorly, but sound tight and natural on well recorded rock, jazz, or classical music. Because of the horn design, you don't have to sit dead center to hear a well defined image of the sound stage. Should be placed on 24"-30" high speaker stands placed about 2' from the rear wall.
Summary: Nice 2 way bookshelf speakers . Once broken in and levels are set right these little horns shine with clarity at high outputs. Can't comment on using the B20s as mains i use them as my 5.1 rear surround channels and they sound great.
Summary: I am no audiophile but the Klipsch speakers have performed very well, tight but not too full lows and clear fresh highs especially female vocalists. Arrived on schedule and undamaged. I am powering with micro system, JVC FS1000,only 13 watts but very satisfying. These speakers are superior to BICs Mod.DV62si that I have been using for12-13 years.
