The Synergy Series SF-2 two-way, floor standing loudspeaker is, hands down, the best sounding passive tower you'll find at such a low price. The SF-2 is square Tractrix? horn-loaded so it's highly efficient, allowing high volumes with low power. Its expert combination of smart new designs and tried and true Klipsch technology provide incredibly life-like music and film sound reproduction. And its wide, deep sound stage and exceptional imaging are typical of all Synergy Series models.
