About the AE520
The Acoustic Energy AE520 is a flagship model in the 500 Series, featuring a multi-driver design with two dedicated 125mm carbon fibre mid-range drivers, three low-frequency drivers, and a 25mm carbon fibre tweeter. This configuration ensures perfect tonal matching across the frequency range. The mid-drivers have oversized 35mm voice coils for low thermal compression and are mounted in sealed enclosures, while the low-frequency drivers are reflex-loaded by a large rear-facing port. The AE520 optimizes vertical directivity to reduce energy wasted on ceiling and floor reflections, enhancing sound clarity compared to traditional designs.
