Klipsch Heritage Heresy IV

➡️ KLIPSCH HERESY IV – THE LEGENDARY SPEAKER AT ITS BEST PERFORMANCE EVER
The Klipsch Heresy IV is the latest and most refined version of one of the most recognizable speakers in the Heritage series. It retains the iconic retro look, but inside the cabinet is an all-new design that significantly increases performance compared to previous generations.
The biggest leap forward is the introduction of VENTED (BASS-REFLEX) CONSTRUCTION, which for the first time in the model's history enables richer, deeper and more controlled bass without losing efficiency. The optimized Tractrix port, new crossover and improved compression drivers combine to deliver a wider frequency range, better dynamics and more natural reproduction of vocals and instruments.
HERESY IV REMAINS ONE OF THE MOST EFFICIENT HI-FI SPEAKERS ON THE MARKET – with a sensitivity of 99dB it delivers impressive sound even with lower power amplifiers, including tube ones. This is a speaker that combines heritage, modern engineering and exceptional character, making it the heart of any audiophile system.
