Because of its size, the Heresy offers the greatest degree of placement flexibility in the Heritage series. First introduced in 1957, this three-way horn-loaded loudspeaker is still able to deliver the awe-inspiring Klipsch sound that our fans around the world know and love.

The Klipsch Heresy IV speaker is a testament to the quality that Klipsch demands from each and every one of its audio products. Remember great sound? We do, too. The Klipsch Heresy enclosure is made in the USA, by proud craftsmen in Hope, Arkansas, just like Paul W. Klipsch (PWK) intended.
