About The Klipsch Forte IV Floorstanding Speakers
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.
High Efficiency, High Performance Loudspeaker: The Forte IV hosts a three-way design utilising a 304.8mm (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 Klipsch’s 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 aided and abetted by the use of a rear-mounted passive radiator. A mammoth 380mm (15") sub-bass radiator at the rear operates on acoustic pressure generated by the active woofer for greater bass output and extension.
Crossover Network: The Forte IV has been completely revoiced from its predecessor, utilising premium componentry in an all new high-fidelity network — minimising 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 & Binding Posts: The Forte’s premium, aluminium input panel accommodates large, high-quality speaker cables. Strong, versatile and quality binding posts provide the capability for bi-wiring or bi-amping.
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 is 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 labelled 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, INDIANA, USA, 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.
Not many manufacturers can boast that they have been producing speakers for over 50 years, make the best selling speaker in the United States and in 1997 have their founder inducted into the Engineering and Science Hall of Fame, an honour shared by Thomas Edison, George Washington Carver and the Wright brothers! The Engineering and Science Hall of Fame recognizes those who have improved the quality of the human condition through an individual contribution using engineering and scientific principles. Klipsch can claim all of the above! But who was Mr. Klipsch or PWK to his friends?
Paul Wilbur Klipsch (PWK) was an American audio pioneer, a true eccentric and a proud member of the engineering and science hall of fame. He gave rise to speaker technologies that would forever impact generations of music lovers. It all started in a tiny tin shed in Hope, Arkansas way back in 1946 when PWK, genius, madman and maverick, designed and hand-built the legendary Klipschorn® speaker with the goal of bringing live music into his living room. In the understatement of the century, we'd say he succeeded. The tin shed is now a full-fledged factory with its own cabinet production line and the company’s headquarters have moved to Indianapolis, Indiana; however, the mission remains to create the world's best speakers.
PWK received a patent on his loudspeaker design in 1945, registered the name Klipsch & Associates in 1946 and began making each loudspeaker with his own two hands until he hired his first employee in 1948. Paul believed in four principles that continue to drive the design of every new Klipsch speaker, today and hopefully tomorrow. High Efficiency: Klipsch utilizes horn-loaded technology in each of its speaker categories, minus headphones and subwoofers, because the horn shape results in accurate and dynamic sound transmission. Low Distortion: Klipsch horn technology reproduces the softest sounds with remarkable clarity and detail and the loudest sounds with no harshness or distortion. Controlled Directivity: Klipsch horn technology assists in accurately directing sound, which, in turn, creates a more lifelike soundstage. Flat Frequency Response: These stunningly accurate speakers offer no unnatural highs, mids or lows, delivering sound as the artist intended.
Our Take On The Klipsch Forte IV Speakers
Klipsch, being Klipsch, call the Forte IV a ‘compact’ horn loaded speaker which is simply hilarious when you consider it has a 12” active woofer on the front and a 15” passive radiator on the rear. Still, some of Klipsch’s other speakers do make the Forte IV’s look rather diminutive so I guess they have a point. So this speaker is never going to disappear in your room, unless you live in a cathedral. But I don’t think buying the Forte IV is about trying to be subtle. It’s probably more about being outrageous and, as Klipsch politely point out, they’ve been pissing off the neighbours with their horn loaded speakers since 1946. Klipsch Forte IV - go big or go home.
