Built with 3/4” tweeter and 8” paper bass driver with copper voice coils, AN-D internal copper cable, internal crossover, copper inductors, chipboard and MDF cabinet, and real wood Black Ash veneers, the AN-K/D is a compact and efficient “book shelf” speaker design that is well-suited for use with low-powered tube amplifiers. 

The AN-K/D’s efficiency and easy load make it a good match with low-powered tube amplifiers. Tube amplifiers tend to have lower power output than solid-state amplifiers. The design allows these speakers to pair well with tube amplifiers, providing excellent sound quality without requiring a lot of power.

The simple design of the crossover consists of hardwire and incorporates air-cored chokes and selected bipolar and polypropylene capacitors in copper foil. The inside of the cable is made of 99.99% pure copper Audio Note (UK) wire.

Its use of two drive units per cabinet provides a wide frequency response and a balanced sound, making it a popular choice among audiophiles and music lovers.
