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 Heritage Series loudspeaker pairs use only book-matched wood veneer panels from the same timber. Veneer leaves are kept in order and arranged to provide a mirror image, like turning the pages of a book.
