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.
DESIGNED AND MADE IN THE USA
USING DOMESTIC AND IMPORTED COMPONENTS
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.
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
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.
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.
