Acoustic Energy AE309² Speakers

The AE309² is a new slim-line floor-standing loudspeaker with compact dimensions, suitable for medium to large sized rooms. Featuring new cabinet design and drivers, performance has been considerably improved in all areas whilst maintaining the same competitive pricing as the previous model.

The AE309² utilises brand-new paper/coconut-fibre bass-mid drivers which were developed using research derived from the CORINIUM project. These drivers, along with an all-new soft dome tweeter are housed in an inert, slimline 18mm constrained-layer RSC™ MDF/bitumen cabinet – offering a significant step up in both audio and material quality at this price point. The slot shaped duct port on the rear of the speaker augments the bass output and has been carefully developed to reduce the effect of air turbulence with a clean, undistorted bass performance.

The cabinet is available in a choice of walnut or newly developed ‘silk-touch’ matte black or white finishes featuring screen-printed logos with trims and grilles which are colour matched for each finish. The new AE309² is also supplied with aluminium feet and spike covers and will easily integrate within any home décor while being considerate to any floor surface.

TECHNICAL INFORMATION

 
 

TWEETER

The 300 Series features a new soft dome tweeter developed from the Corinium project. This tweeter offers exceptional speed, clarity, and low distortion, perfectly matched with our new mid-woofer. Enhanced with the latest WDT waveguide, it ensures low baffle diffraction at crossover frequencies and a wide listening sweet spot at higher frequencies, delivering an open, delicate, and natural treble.

DRIVERS

Discover the newly-developed paper/coconut husk bass-mid drivers in our 300 series, designed for a smooth, natural response. The all-new mid-woofer delivers a warm, natural sound with crystal clarity and dynamic detail. Reinforced with coconut fibers, the cone offers impressive stiffness and reduced breakup modes. The motor structure includes an extended copper pole shield to lower midrange distortion, while a non-conducting voice coil former guarantees impressive bass and dynamic range. Used consistently across the range, this mid-woofer is reinforced in the floor-standing AE320 speaker by two 140mm bass drivers, crafted to the same high standards.

CABINET & DESIGN

The new 300 Series benefits from the same advanced RSC™ cabinets found on our flagship Corinium and range topping 500 Series speakers. This composite material significantly reduces cabinet radiation compared to traditional MDF or Plywood construction, allowing the drive units to perform without interference. This technology is concealed within a design that blends seamlessly into modern interiors with subtlety and elegance. Slimmed-down cabinets and a shift from high gloss to a modern, ‘silk-touch’ matte material with color-coded trims, grilles, and aluminium feet on the floor-standing models.

CROSSOVER

Drawing from the techniques developed during the Corinium project, we’ve significantly reduced distortions in loudspeaker crossover design. By adopting a holistic approach to the woofer, tweeter, and cabinet, we created a crossover filter that offers a lighter touch, minimizing phase distortion and preserving the speakers’ musicality.
