Acoustic Energy AE509 Speakers

Acoustic Energy AE509 is a slimline floorstanding loudspeaker with compact dimensions ideal for medium to large sized rooms. Like the AE500, the AE509 offers a higher performance and finish than the 300 Series.

It features newly developed carbon fibre tweeters and mid/bass drivers designed to match the pistonic precision of the legendary ceramic aluminium drivers with enhanced self-damping for a smoother, more pure sound.

Slimline cabinets

The slimline cabinet is finished in Piano Black, Piano White or American Walnut wood veneer. Solid Aluminium bars ensure rigid floor-coupling and top stability whilst the stiffness of the metal structure reduces interaction between the room and speaker.

These patented drivers are held in new 18mm RSC cabinets evolved from the Reference Series with the same constrained layer composite to greatly minimise cabinet acoustic radiation.


The tweeter incorporates a brand new 25mm carbon fibre dome which is lighter and better damped than other conventional hard dome materials and grants a lightning fast, natural sound that is sure to surprise the listener with its neutrality.

The new cast aluminium WDT waveguide is close to the mid/bass driver for top dispersion and is extremely rigid to lower vibration being passed to the tweeter for sweet, clear and natural highs.


The 125mm mid/bass driver has a new oversized 35mm voice coil for minimal thermal compression and ultra high motor force factor to deliver a highly dynamic yet controlled bass response. The woofer has a maximised motor and suspension system for superior linearity and least distortion for mid-range definition whilst the lightweight carbon fibre cone material enhances transient speed and clarity.


The dual-way crossovers utilise high voltage polypropylene film wound capacitors and air core inductors at key positions for superior dispersion through a more compact acoustic source within the crossover region.
