First introduced in 1957, the Heresy, a three-way design, began as a compact center-channel loudspeaker that accompanied the Klipschorn®. The Heresy IV offers unparalleled sound quality from a relatively small speaker.
- Brand new K-702 midrange compression driver with polyimide diaphragm for exceptional detail
- For the first time, the Heresy IV has a rear port for the most efficient, fastest air transfer in their class, which reduces port noise for more powerful low frequencies
- The midrange of the K-702 is paired with the K-704 Tractrix® horn for a wide coverage pattern
- K-107-TI titanium diaphragm high-frequency driver with an all-new wide-dispersion phase plug for exceptionally even high-frequency dispersion
- Brand new high-fidelity network for more lifelike sound, best-in-class efficiency and load capacity
- Klipsch Tractrix ports have custom-designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass
