Klipsch Forte IV 12" 3-Way Horn-Loaded Floorstanding Speaker RED OAK (Each)
The Klipsch Forte IV is a high-efficiency three-way Heritage Series floorstanding loudspeaker combining a 12" woofer with horn-loaded midrange and high-frequency compression drivers. Its design delivers the dynamic output, clarity and efficiency associated with Klipsch Heritage loudspeakers while maintaining a relatively compact footprint.
An all-new K-702 midrange compression driver with a polyimide diaphragm is coupled to a modified K-703-M Tractrix horn featuring Klipsch Mumps technology for more consistent dispersion throughout the listening area. A K-100-TI titanium-diaphragm compression driver handles the high frequencies, while a 12" K-281 woofer and rear-mounted 15" KD-15 passive radiator provide extended low-frequency performance.
Features:
- 3-Way Horn-Loaded Design - Combines a 12" woofer with horn-loaded midrange and high-frequency compression drivers for high efficiency and dynamic output.
- K-702 Midrange Compression Driver - Uses a 1.75" (4.45 cm) polyimide diaphragm for detailed and dynamic midrange reproduction.
- Modified Tractrix Horn - The K-703-M horn incorporates Klipsch Mumps technology to provide more consistent mid-frequency dispersion throughout the listening area.
- Titanium High-Frequency Driver - K-100-TI 1" (2.54 cm) titanium diaphragm compression driver delivers detailed high-frequency performance.
- Wide-Dispersion Phase Plug - Helps provide more even high-frequency dispersion and a wider listening sweet spot.
- 12" Fiber-Composite Woofer - K-281 woofer provides powerful and controlled low-frequency reproduction.
- 15" Rear Passive Radiator - KD-15 passive radiator extends bass response without requiring a conventional port.
- 99 dB Sensitivity - High efficiency allows the Forte IV to produce substantial output with relatively modest amplifier power.
- High-Fidelity Network - Revoiced crossover network uses premium components to maintain efficiency and signal integrity.
- Bi-Wire / Bi-Amp Capability - Dual binding posts support standard wiring, bi-wiring and bi-amping.
- Heritage Construction - Built using traditional Klipsch Heritage craftsmanship and cabinet construction.
- Made in Hope, Arkansas - The enclosure is made in the USA using domestic and imported components.
