Powerful Acoustic Energy Performance from a Refined Slim-Line Floorstander

The Acoustic Energy AE309² Floor-Standing Speakers (Pair) bring technology developed through Acoustic Energy’s flagship CORINIUM project into a slim floorstanding design engineered for medium-to-large listening rooms. Dual 120mm paper and coconut-fiber bass/midrange drivers combine with a newly developed 29mm fabric-dome tweeter to deliver natural tonal balance, impressive dynamics and room-filling scale without requiring an oversized cabinet.

The completely redesigned enclosure uses Acoustic Energy’s 18mm RSC™ constrained-layer MDF/bitumen construction to reduce cabinet radiation and unwanted coloration. A carefully developed rear slot-shaped duct port reinforces low-frequency output while reducing turbulence, helping the AE309² produce clean, controlled bass down to 33Hz while preserving the open, engaging presentation associated with Acoustic Energy loudspeakers.

Highlights & Benefits

• CORINIUM-Derived Driver Technology — New paper/coconut-fiber drivers apply research developed for Acoustic Energy’s flagship loudspeaker program.
• Slim 2.5-Way Floorstanding Design — Provides room-filling scale and stronger bass extension while maintaining a compact 170mm-wide cabinet.
• RSC™ Constrained-Layer Cabinet — MDF and bitumen layers suppress enclosure vibration so the drivers can reproduce music with less cabinet coloration.
• 89dB Sensitivity — Offers strong dynamic capability and works with a broad range of quality integrated amplifiers and AV receivers.
• Premium Aluminum Feet — Purpose-designed aluminum feet, spikes and protective covers provide stable floor coupling while helping protect hard surfaces.

Technology & Design

120mm Paper/Coconut-Fiber Drivers — Two newly developed bass/midrange units combine paper’s natural tonal qualities with coconut-fiber reinforcement for greater stiffness, clarity and dynamic control.

29mm Fabric-Dome Tweeter — Derived from technology developed for the CORINIUM project, the new soft-dome tweeter provides open, delicate high frequencies with wide dispersion and low distortion.

18mm RSC™ Cabinet Construction — Resonance Suppression Composite construction sandwiches a damping layer within the MDF enclosure to reduce cabinet radiation and preserve acoustic detail.

Rear Slot-Shaped Duct Port — The carefully shaped bass-reflex port augments low-frequency output while minimizing air turbulence for cleaner, less distorted bass reproduction.
