Klipsch Forte IV Heritage Floorstanding Speakers

The Klipsch Forte IV perfectly balances the legendary dynamics of the Heritage Series with room-friendly dimensions, making it one of the most beloved and best-selling speakers in Klipsch history.

A Heritage Favorite Since 1985

Introduced in 1985, the Forte quickly became one of Klipsch's most successful loudspeakers. Designed to deliver much of the scale and dynamics of larger Heritage models while occupying less floor space, the Forte has remained a favorite among audiophiles for decades.

The fourth-generation Forte IV refines the original concept with upgraded drivers, a redesigned Tractrix® midrange horn, an improved crossover network, and enhanced cabinetry while preserving the lively, effortless sound that made the Forte legendary.

The Heritage Sweet Spot

Many enthusiasts consider the Forte IV the ideal balance within the Heritage lineup.

It delivers:

• Large-scale dynamics
• Deep, authoritative bass
• Compact floor footprint
• Exceptional efficiency
• Easy amplifier matching
• Flexible room placement

For many listeners, it offers nearly all the excitement of larger Heritage speakers while fitting comfortably into medium-sized living rooms.

Three-Way Heritage Design

The Forte IV features a carefully engineered three-way loudspeaker system consisting of:

• 12-inch K-281 fiber-composite woofer
• K-702 compression midrange driver
• K-100-TI titanium diaphragm compression tweeter
• Horn-loaded midrange and tweeter

Together these components provide:

• Outstanding transient response
• Exceptional dynamics
• Natural vocals
• Excellent detail
• Low distortion
• High efficiency

Legendary 15-Inch Passive Radiator

One of the Forte's defining characteristics is its large rear-mounted passive radiator.

Unlike conventional bass-reflex ports, the passive radiator provides:

• Deeper bass extension
• Lower distortion
• Greater bass output
• Improved transient response
• Reduced port noise
• Excellent efficiency

This design allows the Forte IV to produce bass performance that rivals significantly larger floorstanding loudspeakers while maintaining a relatively compact cabinet.

New Tractrix® Midrange Horn with Mumps™

The Forte IV introduces an all-new Tractrix® midrange horn.

Benefits include:

• Wider listening area
• Improved imaging
• More consistent frequency response
• Better vocal realism
• Reduced horn coloration
• Greater tonal accuracy

Klipsch's patented Mumps™ geometry further improves off-axis performance, creating a larger sweet spot for multiple listeners.

Redesigned Titanium High-Frequency Driver

The Forte IV also features an upgraded titanium diaphragm compression tweeter.

Enhancements include:

• Wide-dispersion phase plug
• Improved treble extension
• Greater detail retrieval
• More accurate imaging
• Lower distortion
• Better off-axis consistency

These refinements create a more open and natural high-frequency presentation than previous generations.

New Heritage Crossover Network

Klipsch redesigned the Forte IV crossover to improve driver integration.

Benefits include:

• Better phase coherence
• Smoother frequency transitions
• Improved tonal balance
• Enhanced imaging
• Lower distortion
• More seamless presentation

The crossover helps the drivers perform as a unified system while maintaining the lively Heritage sound.

Exceptional Efficiency

With approximately 99 dB sensitivity, the Forte IV delivers impressive performance with surprisingly little amplifier power.

Advantages include:

• Wide dynamic range
• Extremely low distortion
• Effortless musical presentation
• Excellent low-volume performance
• High maximum output
• Compatibility with modest-powered amplifiers

Its high efficiency makes it equally comfortable with premium tube amplifiers and powerful solid-state electronics.

Features include:

• Book-matched real wood veneers
• Precision cabinet construction
• Hand assembly
• Heritage craftsmanship
• Premium finishes
• 10-year Heritage warranty

Each stereo pair is carefully matched for appearance and acoustic consistency.

Amplifier Matching

The Forte IV performs beautifully with a wide range of electronics.

Thanks to its 99 dB sensitivity, even low-powered tube amplifiers can deliver remarkably dynamic, room-filling sound. Many Heritage owners pair the Forte IV with tube amplifiers for its natural tonal balance and effortless presentation.

Room Placement

Unlike the Klipschorn, the Forte IV does not require corner placement.

For best performance:

• Leave 10–18 inches behind the speakers for the passive radiator
• Use slight toe-in toward the listening position
• Maintain symmetrical placement
• Experiment with distance from side walls
• Position the listening chair outside the near field

Allowing adequate space behind the cabinet enables the passive radiator to produce its deepest and most articulate bass. Community owners consistently report improved soundstage depth when the Forte IV is pulled slightly into the room.

Compared to the Heresy IV

The Heresy IV offers:

• Smaller cabinet
• Easier placement
• Lower price
• Compact footprint

The Forte IV adds:

• Deeper bass
• 15-inch passive radiator
• Larger soundstage
• Greater dynamic headroom
• Fuller-range performance

For listeners who want substantial bass without adding a subwoofer, the Forte IV is often the preferred choice.

Compared to the Cornwall IV

The Cornwall IV provides:

• Larger 15-inch woofer
• Greater bass authority
• Higher sensitivity
• Bigger overall presentation

The Forte IV offers:

• Smaller footprint
• Easier placement
• Lower visual impact
• Excellent full-range performance
• Outstanding value

Many listeners consider the Forte IV the perfect compromise between room friendliness and Heritage performance.

Sound Quality

Listeners consistently describe the Forte IV as delivering:

• Explosive dynamics
• Rich midrange
• Fast, articulate bass
• Exceptional imaging
• Lifelike vocals
• Effortless musicality

Its combination of horn-loaded speed, passive-radiator bass, and high efficiency creates an engaging listening experience across virtually every music genre. Owners frequently praise its ability to sound full and dynamic even at modest listening levels.

The Heritage Speaker That Does It All

The Klipsch Forte IV successfully blends Heritage styling, modern acoustic engineering, and room-friendly dimensions into one exceptionally well-rounded loudspeaker.

Its 12-inch woofer, legendary 15-inch passive radiator, redesigned Tractrix® horn, upgraded crossover, handcrafted American construction, and remarkable efficiency make it one of the finest values in high-end loudspeakers.

For music lovers seeking authentic Heritage performance without the size of the Cornwall or La Scala, the Forte IV remains one of the smartest choices in premium two-channel audio.
