Know before you buy
The Heresy IV comes with a slanted riser base that angles the speakers upward toward your ears. While you can place them directly on the floor, using the included riser is recommended for optimal sound dispersion.
Yes, the Heresy IV is one of the most compact floorstanding speakers in the Heritage line. Its design is well-suited for smaller to medium-sized listening rooms where you want high-efficiency sound without the footprint of a massive tower speaker.
Not necessarily. With a sensitivity rating of 104dB, these speakers are highly efficient and can be driven effectively by lower-wattage amplifiers, including tube amps, though they can handle up to 400W peak power if you prefer a more robust setup.
The rear port enhances bass response, but it does mean you should avoid pushing the speakers flush against a wall. Leaving a few inches of clearance will prevent the bass from sounding muddy or boomy.
Absolutely. The Heresy IV is designed to be versatile and performs exceptionally well as a main left and right channel in a home theater system, providing the dynamic range needed for cinematic sound.
The 3-way design uses dedicated drivers for the woofer, midrange, and tweeter, which allows each component to focus on its specific frequency range. This results in clearer vocals, more detailed highs, and better overall accuracy than most 2-way systems.
