Klipsch Forte IV Floorstanding Speakers

Meet the Forte IV Floorstanders - on sale now!

Klipsch's Forte floor-standing speakers have been captivating music lovers since the company introduced them in 1985. New in the 'IV are the redesigned midrange compression driver with a polyimide diaphragm, and a wide-dispersion phase plug in the tweeter. These design tweaks help smooth out the mids and spread the high frequencies into a wider sweet spot.

The Forte IV is designed and hand-built in Hope, Arkansas. It's available in four beautiful wood veneer finishes: Black Ash, American Walnut, Natural Cherry and Distressed Oak.

Klipsch book-matches the veneers for each speaker, providing a beautiful mirror image at the splice joints. And the speaker pairs are grain-matched with wood from the same timber. It's a nice touch, and the kind of attention to detail that sets Klipsch's Heritage line apart.

Klipsch's Heritage Series loudspeakers can be the heart of a party. A college friend of mine had a small room, and a pair of Klipsch Heresies. He'd crank Grateful Dead live recordings, Josh White country blues, or whatever — those speakers never failed to grab your attention. Klipsch's up-front sonic profile lives loud in the Forte IV. Horn-loaded midrange and tweeter sections project inviting, close-to-the-bone clarity.

The Forte IV is a great choice if you like to listen to live recordings. The dynamic energy of inspired performances really reaches out from these speakers — even with a modestly powered amplifier, thanks to the highly efficient 99 dB sensitivity.

The Forte IV

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.

3-Way Design

The Forte IV hosts a three-way design utilising 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 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.

High-Fidelity Crossover Network

The Forte IV has been completely redesigned from its predecessor, utilising premium componentry in an all new high-fidelity crossover 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.

15" Passive Radiator

The Forte IV's well-extended bass is found in the use of a rear-mounted passive radiator. A mammoth 15" in size, this sub-bass radiator operates on acoustic pressure generated by the woofer for greater bass output and extension that results in real full-range performance.
