description Klipsch Heresy II Overview

The Heresy II maintains the Klipsch signature punch while offering a slightly more refined sound than some of their earlier models. They are incredibly efficient, meaning they can produce massive sound levels from relatively modest amplification. This makes them fantastic for genres like blues, rock, and Motown where immediate, punchy energy is required.

They deliver that signature 'Klipsch lift' in the upper mids, making vocals jump out.

help Klipsch Heresy II FAQ

How much amplifier power do Klipsch Heresy II speakers need?

The Heresy II is a highly efficient speaker with a high sensitivity rating, meaning it can produce substantial volume from even a low-wattage tube amplifier. Many owners drive them effectively with as little as 5 to 10 watts per channel, though they also perform well with higher-powered solid-state amplification.

What is the difference between the Klipsch Heresy II and Heresy III?

The Heresy III features an updated crossover network and a redesigned titanium tweeter diaphragm, resulting in smoother high-frequency response compared to the Heresy II. The II is often preferred by enthusiasts for its punchier, more aggressive midrange character.

Do Klipsch Heresy II speakers need a subwoofer?

The Heresy II has limited bass extension, typically rolling off below roughly 50–60 Hz, due to its relatively compact sealed cabinet. Adding a subwoofer fills in the bottom octave for home theater use, though many owners find them satisfying for music without one.

What years were the Klipsch Heresy II speakers manufactured?

The Heresy II was produced from the mid-1980s through the mid-2000s before being succeeded by the Heresy III. Many vintage pairs remain in circulation on the used market, often in excellent condition due to their durable birch or walnut plywood construction.
