Acoustic Energy 520
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 fiber to provide perfect tonal matching across the frequency range.
The two dedicated 125mm carbon fiber 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 reflexly 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.
The slim-line cabinets are finished in Piano Gloss Black, Piano Gloss White or American Walnut wood veneer finishes. Solid Aluminum bars are supplied to ensure rigid floor-coupling and maximum stability, whilst the stiffness of the metal structure reduces the room to speaker interaction.
Technical specifications
TWEETER
Our 500 Series tweeter features a brand new 25mm carbon fiber dome. Carbon fiber 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 aluminum 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 optimized motor and suspension system for maximum linearity and lowest distortion ensuring mid-range definition, whilst the lightweight nature of the carbon fiber 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 utilizes a 3 way design.CABINET
These unique drivers are housed in our new 18mm Resonance Suppression Composite (RSC) cabinets, evolved from the prestigious Reference Series and featuring the same constrained layer composite to greatly reduce cabinet acoustic radiation, which would otherwise color the sound.
