High Performance is Our Forte

Since its inception in 1985, the Forte has been a standout speaker. The new Forte IV features updated cosmetics and the latest advancements in acoustic engineering for premium performance.

Best-In-Class Efficiency & Premium Performance

The titanium diaphragm high-frequency driver has a new wide dispersion phase plug for a wider, more accurate sweet spot.

An all-new K-702 midrange compression driver ensures exceptional detail and dynamics.

The Tractrix® horn, featuring our patented Mumps technology, gives you more consistent sound throughout the listening area.

Legendary Technology

Don't Mess With Perfection

The Forte IV enclosure is hand-assembled in the USA, by proud craftsmen in Hope, Arkansas, just like Paul W. Klipsch intended.

Book-Matched Wood Veneer

Klipsch only uses book-matched wood veneers for the Heritage series. The veneer leaves are kept in order and arranged to provide a mirror image, like turning the pages of a book.

Matched Pairs

Heritage Series loudspeaker pairs are grain-matched using wood veneer panels from the same timber. Each cabinet is carefully matched so each speaker in a pair is practically indistinguishable from the other.
