Klipsch Heresy IV – Compact Heritage Horn-Loaded Floor-Standing Speaker

The Klipsch Heresy IV revives a vintage classic in a more compact package, delivering bold, dynamic sound through horn-loaded drivers and a powerful 12″ woofer. With modern acoustic updates and timeless American craftsmanship, it’s ideal for both music lovers and home cinema systems that demand real presence with heritage style.

Key Features

Horn-loaded compression drivers: A polyimide-diaphragm K-702 midrange on a Tractrix horn and a titanium-diaphragm K-107-TI tweeter with a wide-dispersion phase plug ensure precise, spacious imaging.

Revoiced crossover network: Premium components and AudioQuest wiring minimise signal loss and support high efficiency and detail.

New Tractrix rear port: This first-in-series rear port enhances bass extension by nearly 10 Hz, with flared design reducing port noise for tighter, punchier lows.

Heritage build quality: USA-assembled cabinet with book-matched wood veneer, bi-wire/bi-amp capable binding posts, and a slanted riser base that’s removable for shelf placement.
