HIGH PERFORMANCE IS OUR FORTE

First introduced in 1985, the Forte quickly established itself as the most popular

Klipsch model. The elegant design and outstanding performance made the Forte a

standout among its competitors. In 2017, Klipsch re-introduced the Forte as part of the

Heritage speaker series. The new Forte IV features updated cosmetics and the latest

advancements in acoustic engineering, while maintaining the original charisma that

made the Forte so popular.

Don’t mess with perfection. We’ve made some important upgrades to the Forte IV,

but it remains relatively unchanged since its inception. Remember great sound?

We do, too. The Forte IV enclosure is still made in the USA, by proud craftsmen in

Hope, Arkansas. Just like Paul W. Klipsch (PWK) intended.

HIGH EFFICIENCY, HIGH PERFORMANCE LOUDSPEAKER

The Forte IV hosts a three-way design utilizing a 12” woofer and horn-loaded midrange

and tweeter. The Forte IV incorporates an all new K-702 midrange compression driver,

featuring a polyimide diaphragm for exceptional detail and dynamics. The K-702

midrange is mated to a modified Tractrix® horn — featuring our patented Mumps

technology for even polar response of mid frequencies, giving you more consistent

sound throughout the listening area. The titanium diaphragm high-frequency driver has

an all-new wide dispersion phase plug for providing exceptionally even high-frequency

dispersion for a wider, more accurate sweet spot.

PASSIVE RADIATOR YIELDS FULL RANGE PERFORMANCE

The Forte IV’s well-extended bass is found in the use of a rear-mounted passive radiator.

A mammoth 15” (38 cm) in size, this sub-bass radiator operates on acoustic pressure

generated by the active woofer for greater bass output and extension.

NETWORK

The Forte IV has been completely revoiced from its predecessor, utilizing premium

componentry in an all new high-fidelity network — minimizing electrical degradation

throughout the circuitry — for truer to life sound with best in class efficiency and power

handling. The new network draws from the classic three-way steep slope design of the

legendary Klipschorn and La Scala speakers.

BI-AMP INPUT PANEL AND BINDING POSTS

The Forte’s premium, aluminum input panel accommodates large, high-quality speaker

cables. Strong, versatile and quality binding posts provide the capability for bi-wiring

or bi-amping.

FEATURES

BOOK-MATCHED WOOD VENEER

Klipsch only uses book-matched wood veneers for the Heritage series. The veneer

leaves are kept in order as they are delicately sliced from the timber and precisely

arranged to provide a mirror image at the splice joint — like turning the pages of a

book. This gives each speaker an aesthetically appealing and consistent appearance

that is treasured more than any other cut of wood veneer.

MATCHED PAIRS

Every pair of Heritage series loudspeakers are grain-matched using wood veneer

panels that come from the same timber. Each cabinet is carefully matched so that each

speaker in the pair is practically indistinguishable from the other. The speakers move

seamlessly together through the factory, and each finished product is inspected and

labeled with sequential serial numbers, ensuring that your Heritage series speakers

leave the factory as a meticulously crafted set.

BUILT TO LAST

While each and every component of the Forte IV is built to last, Klipsch has always

recognized the unique and critical role of a loudspeaker’s cabinet in the sound

reproduction process. From the craftsmen in Hope, AR to the engineers in Indianapolis,

IN, Klipsch has always put an extraordinary emphasis on cabinet design. The Forte

enclosure is assembled using only the highest-grade adhesives and fasteners. This is a

speaker you will hand down from generation to generation.
