The All-New Acoustic Energy AE309² at Audio T Cheltenham
/Fresh from making waves as one of the standout new releases at the recent Bristol Hi-Fi Show, we have now just taken delivery of our demonstration pair of the brand new Acoustic Energy AE309². Are they any good I hear you all ask? Well, after giving them a jolly good run-in on our main shop system, they’re now set up in the demo room for a more critical, in-depth listen!
The Acoustic Energy AE309²
Out With The Old…
We’ve been selling Acoustic Energy loudspeakers for quite some time now, and they’ve consistently impressed by delivering performance that punches well above their price point. The original AE309 has been one of our best-selling compact floor-standing loudspeakers for a while, so when we heard a Mark 2 version — or ², as they’ve named it — was on the way, we weren’t sure they could improve on an already fantastic speaker.
Well, improve it they have — and by no small margin!

…In With The New
The new Acoustic Energy AE309² benefits significantly from trickle-down technology, courtesy of the flagship Corinium loudspeaker. In fact, it shares no components with the previous model — this is a complete redesign.
The AE309² features brand-new paper and coconut-fibre bass-mid drivers, developed using research from the Corinium project. These are housed in an inert, slimline 18mm MDF cabinet, using constrained-layer damping with bitumen for improved rigidity and reduced resonance — a notable step up in both sound and build quality at this price point. Around the back, the slot-shaped bass port has been carefully engineered to minimise air turbulence, delivering clean, undistorted low frequencies.
A newly designed soft-dome tweeter, also inspired by the Corinium, provides open, delicate, and natural high frequencies, blending seamlessly with the mid-woofer for a cohesive, balanced performance across the entire audible range.
“I Like Your Top”
A sturdy set of solid aluminium feet and spikes act as outriggers, providing excellent stability and preventing the cabinet from rocking on the floor. A more stable speaker isn’t just practical — it enhances imaging and soundstaging too, delivering a more precise and immersive listening experience.

“Bottom’s Quite Nice Too”

The speaker connections are a pair of solid, gold-plated 4mm sockets — ready to accommodate banana plugs, spades, or even bare-ended cable with ease.
Round the back, the slot-shaped duct port enhances bass output and has been carefully engineered to minimise air turbulence, delivering clean, undistorted low frequencies. This clever design also means you can position the speakers closer to a rear wall without introducing any unpleasant bass boom — perfect for tighter spaces.

History And Science Fiction
To put the new Acoustic Energy AE309² speakers through their paces, my first choice was History and Science Fiction by guitar virtuoso Chris Forsyth and the Solar Motel Band. The track comes from the 2017 album Dreaming In The Non-Dream, which I believe was released as a sort of anti-Trump protest howl against the destruction of the American Dream — makes me wonder how he feels now!
streamy goodness
The album is short, clocking in at around 35 minutes, and has a raw, live feel. This track, just shy of 10 minutes, builds into a steadily evolving psych-infused art-rock jam. It’s a mutant blend of Marquee Moon-era Television and a Grateful Dead live space-out, with a full-fat, funky Velvet Underground meets God vibe running through it. There’s even a breakdown that’s pure prog rock — plus a surprise Roxy Music-esque sax moment toward the end, just for good measure. And here’s the kicker: it’s not even the best track on the album.
The AE309² speakers were nothing short of stunning. The soundstaging stretched far beyond the cabinets, creating a massive, immersive space. The bass was deep, weighty, and seamlessly integrated with a wonderfully open midrange. Topping it all off, the new tweeter is a thing of beauty — smooth, sweet, and brimming with detail, letting me peer right into the heart of the mix.
No Fluke
Acid fried guitar freak out beauty
Just to make sure this wasn’t some kind of strange fluke, I figured I’d better try another track. This time, I went with Magic Mountain by Hollow Ship, from their album Future Remains.
Hollow Ship are a four-piece psychedelic rock band from Gothenburg, blending the sounds of early British psych with mind-expanding, funky Afro-rock grooves. Their music fuses sweet, 1960s analogue sonics with modern production techniques, creating a sound that’s uniquely their own.
Once again, the Acoustic Energy AE309² delivered in style — infusing the track with an infectious, bouncy energy and a swaggering, acid-soaked, guitar-drenched vibe. An air-guitary, psych-rock fever dream brought to life.
So, definitely not a fluke then!
The Best Just Got Better
To sum up — the best has indeed just got better. There’s now a sizeable gulf between the new AE309² and the rest of the competition, who’ll need to seriously up their game to avoid being left behind. These compact floor-standing marvels have no right to sound this good for the price.
In line with modern furniture trends, Acoustic Energy has moved away from the high-gloss finishes of the previous 300 Series. Instead, the AE309² comes in a newly developed, highly durable 'silk-touch' black or white matte finish, or a classic walnut wood veneer — all paired with colour-coordinated trims and premium fabric grilles for a refined, contemporary look.
Sonically, they’re an exciting, exhilarating, and incisive listen — and they absolutely deserve a spot at the top of any serious shortlist of loudspeakers to demo this year.
