About the Heresy
The Klipsch Heresy is a compact, three-way loudspeaker first introduced in 1957 as a center speaker for three-channel systems built around the Klipschorn. The current Heresy IV retains the model’s horn-loaded midrange and high-frequency design, paired with a 12-inch woofer. It uses a rear-firing Tractrix port and is available in wood-veneer finishes.
