Acoustic Energy AE520
“They’re as enjoyable and as information-packed at very low volumes, and they don’t get shouty or coarse when you turn the wick up — they simply get louder.”
— Hi-Fi+
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.

Key Features
TWEETER
Our 500 Series tweeter features a brand new 25mm carbon fibre dome. Carbon fibre is much lighter and better damped than other typical hard dome materials and provides a lightning fast, natural sound which will surprise the listener with its neutrality. The new cast aluminium WDT waveguide on the high frequency driver is positioned close to the mid/bass driver for optimum dispersion and is extremely stiff to reduce vibration being passed to the tweeter, ensuring sweet, clear and natural highs.
DRIVERS
The 125mm mid/bass driver includes a new oversized 35mm voice coils for low thermal compression and very high motor force factor, to provide a highly dynamic yet controlled bass response. The woofer has an optimised motor and suspension system for maximum linearity and lowest distortion ensuring mid-range definition, whilst the lightweight nature of the carbon fibre cone material increases transient speed and clarity.
CROSSOVER
The crossovers use high voltage polypropylene film wound capacitors and air core inductors at critical locations for optimum dispersion through a smaller acoustic source size within the crossover region.
The AE509 is a Mid Tweeter Mid/Bass (MTM) driver layout and both models use a 2 way crossover, whilst the AE520 utilises a 3 way design.
