About the Klipsch Heresy IV Floorstanding Speaker
At Rapallo, the Klipsch Heresy IV Floorstanding Speaker is one of the most fun and engaging speakers in the Heritage range.
It delivers that unmistakable Klipsch sound, fast, dynamic and highly expressive, while being more compact and easier to place than larger models like the Forte or Cornwall. The addition of a rear port in the IV version gives it much better bass extension, making it far more versatile than earlier generations.
This is an exceptional choice for customers running tube amplifiers or lower-powered systems, as the high sensitivity allows it to come alive with very little power.
The Klipsch Heresy IV is available for demonstration at Rapallo AV, so you can experience its speed, energy and musicality in a properly set up system.
