KLIPSCH HERESY

A LITTLE HERESY IS GOOD FOR THE SOUL

First introduced in 1957, the Heresy IV is quite possibly the speaker champion of the world.

For the first time in its long legacy, the Heresy now features a rear port – improving low-frequency extension by almost 10Hz, for room-filling bass.

Utilizing Tractrix geometry, the all-new Heresy IV ports allow for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies. 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.

AVAILABLE IN CHERRY, WALNUT, BLACK ASH, AND DISTRESSED OAK
