Klipsch Outstanding Quality

These speakers are beautifully crafted and are a shining example of the wonder of Klipsch's American craftmanship. 50 years of design results in an unparalleled build quality that can be seen throughout their product catalogue. The cabinets on the Hersey's are built to last by using the highest grade materials to ensure the best sound reproduction process.

Real Wood Veneer

Alongside the quality build of the Klipsch Heritage Heresy IV speakers, the exterior finish has also been beautifully done. Each pair of these speakers are grain-matched using real wood veneer made from the same timber to ensure the highest consistency between pairs. The four different wood finishes are meticulously perfected and ensure the most premium aesthetic is achieved.

All New K-702 midrange driver

Given its compact size, the Heresy IV are highly efficient. They are small in size but big in sound. Featuring a 3-way design that utilises a 12 inch woofer, horn-loaded midrange compression driver and tweeter. The new midrange driver features a polymide diaphragm for improved details and dynamics. Coupled to the K-704 Tractrix horn the midrange provides a wide coverage pattern and smooth frequency response.

Tractrix Ports

The Klipsch Heritage Heresy IV Speakers now features a rear port - a first time for the Heresey series. This improves the low frequency response by almost 10hZ so that a floor filling bass can be achieved. The new Hersey V1 port utilises Tractrix geometry and custom made inner flares which minimise air turbulence and port noise. The result is a punchier and more powerful bass performance.
