Product Information

The AE509 is a slim-line floor-standing loudspeaker with compact dimensions, suitable for medium to large sized rooms. Similar to the AE500 comparison, the AE509 offers higher levels of performance and finish than its 300 Series equivalent. The 500 Series features Acoustic Energy's newly developed carbon fiber tweeters and mid/bass drivers, designed to match the pistonic power and accuracy of Acoustic Energy's legendary ceramic aluminum drivers but with improved self-damping for a smoother, more transparent sound. Offering unparalleled levels of performance, quality and value the result is an audio product with clean, uncluttered lines delivering a thrilling and powerful presentation discerning Acoustic Energy owners have come to expect for over 30 years.

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.


Acoustic Energy's 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.


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.


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.


These unique drivers are housed in Acoustic Energy's 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.
