The KLH 4 features a ported two-way design that used a poly cone 6½" mid/bass woofer with huge magnet structure and 1" soft dome tweeter. That non-EIA format reference/date code on the magnet covers tells us that both drivers were made by Peerless of Denmark at their second factory in Massachusetts. These capable drivers are housed in reasonably-sized, yet notably heavy cabinets measuring 12½" tall x 8¼" wide x 7⅜" deep (incl. grille but not terminals), crafted of thick fiberboard covered on four sides with attractively-grained real walnut veneer. They blend effortlessly with just about any type of décor while being about as heavily constructed as one would ever need. Please check out the photos.
