The accordion-like folded cone of the tweeter was specially developed for the Evo4 series. It consists of two shelf loudspeakers with downfiring bass ports (500 or 750 Euro/pair), which can be placed close to the wall, and two floorstanding loudspeakers (1300 or 1500 Euro/pair), as well as two centre loudspeakers (500 or 700 Euro) and the Evo 4.S surround speaker for home cinema systems. The bass is provided by 13 or 17 cm Kevlar cones. The three-way models also feature a 2-inch dome midrange driver. The complete series is now available in black, white and walnut.
