Acoustic Energy AE309² Speakers

About The Acoustic Energy AE309² Speakers

The AE309² is a 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 competitive pricing of 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.

The new 300 Series marks a milestone in loudspeaker design. It proudly stands on the shoulders of the Corinium project, utilising its insights to elevate Acoustic Energy’s mid-product range to a level unequalled at the price. No single component has been shared with the previous 300 Series, showcasing a completely new acoustic and aesthetic design from the ground up. This transformative venture has redefined Acoustic Energy’s understanding of speaker design, highlighting what truly matters in achieving exceptional sound quality.

The all-new mid-woofer, crafted with a blend of paper and coconut husk, delivers a smooth, natural and refined response, embodying warmth and clarity while retaining the punch and pace of the previous aluminium cone. This ground breaking new driver ensures consistent sonic performance across the range. Partnered with a newly developed soft-dome tweeter derived from Acoustic Energy’s Corinium project, it offers open, delicate and natural high frequencies, tonally matching with the mid-woofer to enable seamless integration across the audible range.

A first at this price point, the new 300 Series features constrained-layer RSC™ (Resonance Suppression Composite) cabinets pioneered in Acoustic Energy’s Reference Series nearly 15 years ago. This advanced construction significantly reduces cabinet radiation, allowing the drive units to perform at their best without enclosure interference, ensuring pure, uncoloured and natural sound.

The 300 series doesn’t just sound good; it looks good too. Acoustic Energy’s design team have created an aesthetic that blends into modern interiors with subtlety and elegance, including bespoke trims and grilles for each finish creating a more harmonious design language.

In line with latest furniture trends, Acoustic Energy have moved away from the high gloss finishes of the previous 300 Series and chosen a newly developed, modern and highly durable ‘silk-touch’ matte material with colour-coordinated trims and matching premium grille fabrics. The result is a fresh design statement which remains distinctly Acoustic Energy.

The AE309² is an audio product with clean, uncluttered lines, delivering the thrilling and powerful presentation which discerning Acoustic Energy owners have come to expect for over 35 years.

The finish options are bang on trend, with a gorgeous matte black, white, or walnut look that integrates effortlessly into modern interiors. You also get quality-of-life touches like colour-matched grilles and elegant aluminium feet.
