Acoustic Energy AE509 Floorstanding Loudspeakers Pair in Piano Gloss White

Acoustic Energy AE509 Floorstanding Loudspeakers – Slim Design, High-End Sound

The Acoustic Energy AE509 is a premium floorstanding loudspeaker engineered for music lovers who demand both performance and elegance. With its slim-line cabinet and compact footprint, the AE509 is ideal for medium to large-sized listening rooms, delivering room-filling audio without dominating your space.

Built as part of the acclaimed 500 Series, the AE509 introduces next-generation carbon fibre drivers that combine precision, speed, and control. Designed to outperform traditional ceramic aluminium cones, these drivers provide a smoother tonal balance, exceptional clarity, and fast transient response, ensuring every note is reproduced with lifelike detail.

Key Features of the Acoustic Energy AE509

• Carbon Fibre Dome Tweeter (25mm): Lightweight and well-damped for crystal-clear highs with natural detail.

• Dual Carbon Fibre Mid/Bass Drivers (125mm): Fast, dynamic response with extended low frequencies and refined midrange.

• Advanced Crossovers: High-quality polypropylene capacitors and air-core inductors ensure seamless driver integration.

• Resonance Suppression Composite (RSC) Cabinet: Minimises unwanted resonance for a clean, neutral sound signature.

• Premium Finishes: Choose from Piano Gloss Black, Piano Gloss White, or American Walnut veneer to suit your interior.

• Stable Aluminium Floor Bars: Enhance rigidity and reduce interaction with room acoustics for a more controlled performance.

Designed for Performance and Precision

At the heart of the AE509 is a new carbon fibre tweeter, paired with Acoustic Energy’s Wide Dispersion Technology (WDT) waveguide. This ensures smooth, even high-frequency distribution, creating an expansive soundstage that reaches every corner of the room.

The dual 125mm carbon fibre drivers are engineered with oversized 35mm voice coils, offering both control and dynamics. From deep, punchy bass to articulate mids, the AE509 handles every genre with authority and finesse.

Cabinet Engineering Excellence

Drawing inspiration from Acoustic Energy’s flagship Reference Series, the AE509 uses an 18mm Resonance Suppression Composite enclosure to suppress unwanted cabinet vibrations. The result is an uncoloured, transparent sound that lets your music shine as intended.
