Klipsch Heresy MK4


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 fans around the world know and love.

  • All-new high fidelity network
  • Features a rear Tractrix port
  • Designed & assembled in the USA


A glorious mix of grippy, deep bass, a forceful mid-range and sparkly highs. Lovers of the ‘horn sound’ – where music comes across as direct and snappy – are well served, but when needed there’s also sufficient nuance and intimacy to the Heresy IV’s delivery to make the high-end price point palatable. Above all, the Klipsch cabinets sound brilliantly fun, making other loudspeakers feel dull by comparison”.  HCC. Nov 2021
