The Extreme Mk II model is constructed with two modules (upper and lower). The upper module can be adjusted in the range of 300mm in height. To make the positioning process more convenient we set nine different steps in this range, so the top module of the speakers can be moved up or down. For this process, both speakers are connected to a controller box and the height of both speakers can be changed simultaneously with the dedicated remote control. This adjustment process is crucial in setting up the loudspeakers. The upper module has a curved front panel. Combined with the Cell concept drivers, the time alignment in the listening position is preserved. The motion of the upper module follows a curved trajectory, helping to maintain focus on the desired height
