Pair of Emerald Physics CS2 speakers in very good condition and with the Behringer Ultradrive Pro modified by AudioSmile for even cleaner sound. No flaws, snags, holes, or dents anywhere. These are open baffle and deliver that airy sound when you set them about three feet from the back wall. They use active EQ and require bi-amplification, so you need four power amp channels to drive this stereo pair. They are especially great for percussion, including drums and piano, because the speakers deliver transients with great punch. They give enough bass for most music, but they are open baffle, so for movies I would add a powered sub. Am selling these because I bought MartinLogan electrostats.
