The AE520 is a powerful, slim-line, floor-standing loudspeaker which builds on the AE500 and AE509 models to firmly establish itself as the brand's new flagship, featuring multi-driver design, imposing size and performance. The AE520 features two dedicated 125mm mid-range drivers, three low frequency drivers and a 25mm tweeter – all fashioned from carbon fibre to provide perfect tonal matching across the frequency range. The two dedicated 125mm carbon fibre mid-drivers include new oversized 35mm voice coils for low thermal compression and optimum motor force factor. Both are mounted within their own dedicated sealed enclosure whilst the three dedicated low frequency drivers are reflex loaded by a large rear facing rectangular port. Designed to match the pistonic power and accuracy of our legendary ceramic aluminum drivers, these new units offer much improved self-damping for a smoother, more transparent sound. Vertical directivity has been optimized to provide excellent vertical coverage whilst reducing the energy otherwise wasted on ceiling and floor reflections when compared to traditional designs.
