Klipsch Forte III Heritage Series Floorstanding Loudspeaker (Each)

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 III 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 III hosts a three-way design utilizing a 12” woofer and horn-loaded midrange and tweeter. The new Forte III utilizes all new state of the art drivers including midrange and tweeter titanium compression drivers for a smooth and powerful response. The Forte III’s new midrange horn utilizes patented technology to improve coverage and control of the key mid-frequency band.

    Passive Radiator Yields Full Range Performance

    In the back of the cabinet, the Forte III has a secret. The Forte III’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 woofer for greater bass output and extension.

    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 a more aesthetically appealing and consistent appearance that is treasured more than any other cut of wood veneer.

    Matched Pairs

    Each pair of Forte III 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 that each pair of speakers leave the factory as a meticulously crafted set.

    Built to Last

    No detail goes unnoticed. Klipsch speakers are built to rock the house and stand the test of time. The Forte III is meticulously handcrafted and assembled using the finest quality materials, even down to the highest-grade adhesives and fasteners. This is a speaker that will be handed down for generations to come.
