Klipsch Heresy IV 12" 3-Way Horn-Loaded Floorstanding Speaker RED OAK BLACK (Each)

The Klipsch Heresy IV is a compact three-way Heritage Series loudspeaker that combines high efficiency, horn-loaded midrange and high-frequency drivers, and a powerful 12" woofer. The fourth generation introduces a rear-firing Tractrix port for improved low-frequency extension while retaining the dynamic, highly efficient performance that has defined the Heresy since its introduction in 1957.

A K-702 midrange compression driver with a polyimide diaphragm is coupled to a K-704 Tractrix horn featuring Klipsch Mumps technology for consistent dispersion throughout the listening area. High frequencies are reproduced by a K-107-TI titanium-diaphragm compression driver, while a K-28-E 12" fiber-composite woofer and rear-firing Tractrix port provide strong, controlled bass performance.

Features:

• 3-Way Heritage Design - Combines a 12" woofer with horn-loaded midrange and high-frequency compression drivers.
• K-702 Midrange Compression Driver - Uses a 1.75" (4.45 cm) polyimide diaphragm for detailed and dynamic midrange reproduction.
• Tractrix Midrange Horn - K-704 horn incorporates Klipsch Mumps technology for improved coverage and dispersion.
• Titanium High-Frequency Driver - K-107-TI 1" (2.54 cm) titanium diaphragm compression driver provides detailed high-frequency reproduction.
• Wide-Dispersion Phase Plug - Helps provide more consistent high-frequency dispersion throughout the listening area.
• 12" Fiber-Composite Woofer - K-28-E woofer delivers powerful low-frequency performance.
• Rear-Firing Tractrix Port - Improves airflow and extends low-frequency performance compared with previous generations of the Heresy.
• 99 dB Sensitivity - High efficiency enables substantial output from relatively modest amplifier power.
• Premium Input Panel - Dual binding posts provide secure connections and support bi-wiring and bi-amping.
• Book-Matched Wood Veneer - Real wood veneer panels are arranged to provide a matched appearance.
• Slant Riser Base - Positions the loudspeaker at an upward angle for proper listening orientation when placed on the floor.
• Made in Hope, Arkansas - The enclosure is made in the USA using domestic and imported components.
