Be the Life of the Party: Horn-Loaded Klipsch Forte IV Floor-Standing Loudspeakers Feature 15-Inch Passive Radiator, 12-Inch Woofer, and Gorgeous Looks

Updated with a new wide-dispersion high-frequency phase plug, steep-slope crossover network drawn from Klipschorn AK6, K-702 midrange compression driver, and floating riser, the Klipsch Forte IV floor-standing loudspeakers are expressly designed to serve as the life of the party.

Yes, they execute critical aural qualities must fans love, and do so with panache at both soft and loud volume levels. But at heart, the 72-pound Forte IV is all about the energy, enthusiasm, enjoyment, passion, and turn-it-up-to-11 zest that comes from experiencing a favorite song, cherished album, iconic artist, and/or stimulating new work in a way that makes you believe you're one of the musicians. Think back to the first time you heard music that made you want to strum an air guitar, blow an imaginary saxophone, jump up on a couch and lip-sync lyrics, lead an invisible orchestra, or dance around the room with abandonment. Now, imagine how good that would feel again, anytime you wanted. Enter Forte IV.

Hand-assembled in Arkansas, the U.S.A.-built Forte IV claims a heritage that stretches back to its original introduction in 1985 when it quickly became Klipsch's best-selling model. By its very nature, this full-range horn-loaded design boasts a high-efficiency rating that practically invites pairing with tube amplifiers. You won't need much to drive it and fill your room with sound. Similarly, Forte IV's narrow dispersion translates into straightforward projection that lessens refractions and vibrations. And Forte IV can be placed close to walls, freeing up space and giving listeners with space constraints more options. It also serves as a choice speaker for home-theater applications.

Distinguished on its rear side with a massive 15-inch passive radiator that moves in tandem with and reinforces an active 12-inch woofer, Forte IV specializes in the type of deep low-end responsiveness – extended, clean, crisp, taut, controlled – that finishes notes, phrases, and harmonics with concert-like realism. If you're seeking the ultimate in black-tie refinement or politeness, you may want to look elsewhere. Forte IV doesn't hold back and doesn't apologize. It came to rock. To that extent, a new K-702 midrange compression driver and one-inch horn-loaded titanium tweeter supply smooth, attention-getting sonics marked by full-range breadth, control, and focus. An enhanced phase plug, large voice coils, the aforementioned steep-slope crossover network, and a beefy input panel further account for Forte IV's mesmerizing charisma.

As do the handcrafted retro-cool aesthetics, the result of book-matched wood veneers that allow each speaker to look exactly like the other – and showcase stunning consistency for your decor. What's more, Forte IV's relative thinness – each speaker measures just 13 inches deep – means you'll have floor space to spare while sacrificing none of the sound. Its updated floating riser helps put it at a proper listening level while presenting the illusion that the speaker floats on air. Add in Klipsch's incredible 10-year manufacturer warranty and our Satisfaction Guarantee, and you've got nothing to lose by auditioning Forte IV in your home today.

“The Forte IVs fast, crisp, lively-sound engages your interest and touches the emotions. There’s nothing cerebral about the Forte IV. The sonic presentation is full-blooded and immediate, with impressive scale, depth, and clarity. It’s exciting and visceral; agile and responsive.”
—Jimmy Hughes, Hi-Fi+

Book-Matched Wood Veneers

Klipsch only uses book-matched wood veneers for 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 a more aesthetically appealing and consistent appearance that is treasured more than any other cut of wood veneer.

Matched Pairs

Each 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. Each finished product is inspected and labeled with sequential serial numbers, ensuring Heritage Series speakers leave the factory as a meticulously crafted set.
