Product Overview
The Klipsch Forte IV is a modern evolution of one of Klipsch’s most celebrated loudspeakers. First introduced in 1985, the Forte series has earned a reputation for delivering a room-filling soundstage, exceptional efficiency and a uniquely natural tonal balance.
The latest Forte IV features a completely redesigned midrange horn, updated drivers, improved bracing and a premium crossover network inspired by Klipsch’s flagship models. The result is a speaker that retains the emotional impact of classic Klipsch Heritage while offering greater smoothness, detail and acoustic refinement.
Listening Experience
The Forte IV pair delivers a rich, spacious and effortlessly dynamic listening experience. The horn-loaded titanium compression driver offers exceptional clarity and immediacy, allowing vocals and instruments to sound vivid and lifelike.
The 12" woofer, combined with the large 15" passive radiator, produces deep, tuneful and highly controlled bass without the need for massive amplifier power. The midrange is open and expressive, while the treble is detailed yet remarkably smooth for a horn design.
The soundstage is wide, three-dimensional and holographic, making the Forte IV particularly captivating for acoustic recordings, jazz, classical music and live performances.
Recommended Room Size
Best suited for medium to large rooms. The rear passive radiator benefits from placement 20–45 cm away from the wall to achieve optimal bass integration and room loading.
Amplifier Pairing
With their high sensitivity, the Forte IV pair performs beautifully with amplifiers offering 20 to 120 watts per channel. Their efficiency makes them compatible with a wide variety of amplification styles.
• Tubes add warmth, dimensionality and natural richness—an exceptional match for the Heritage sound.
• Solid-state amplifiers deliver precision, control and impactful bass.
