Large floor-standing loudspeakers provide a lot of space to accommodate elaborate technology and powerful drivers. However, it gets really tricky when we try to get the perfect sound out of very compact speakers. We have developed the Light Weight Dome, an extremely compact tweeter, precisely for this area of application. Its extremely light membrane provides for outstanding impulse fidelity and dynamics up to beyond the audible range. At the same time, it is very resilient and also ensures top-class sound in compact loudspeakers.
