About this item

• All-new K-702 midrange compression driver, featuring a polyimide diaphragm, for exceptional detail
• For the first time, the Heresy IV features a rear port 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
• Designed & assembled in the USA
